Best ResponseYou've already chosen the best response.0Can you tell me the formula for Area of Rectangle?

Best ResponseYou've already chosen the best response.0You have been given Length = 8 cm and Width = 6 cm.. I want to know if you know the formula to find Area of a Rectangle or not?

Best ResponseYou've already chosen the best response.0And please, if you don't know anything I am asking, then say frankly and boldly that you don't know, I am here to make you know everything.. Don't worry about that.. Now, let us have some interaction so that we can both solve it properly and can understand it..

Best ResponseYou've already chosen the best response.0Okay, I tell you, suppose we have a rectangle with its length = l (el) cm and width = w cm..

Best ResponseYou've already chosen the best response.0So, now we need to find its Area, I tell you that Area of any rectangle is given by: Area = Length x Width.. Did you get this?

anonymous

Best ResponseYou've already chosen the best response.0So, the Rectangle that I have draw with l cm and w cm is having area of: \(Area = l \times w = lw \quad cm^2\)..

Best ResponseYou've already chosen the best response.0Clear upto this? Any doubt?

Best ResponseYou've already chosen the best response.0hm, when i multiply the actual length by the width of my rectangle i come up with 48. Is that how I am supposed to do this?

anonymous

Best ResponseYou've already chosen the best response.0I am just telling your the basic formulae that we need to solve your original problem..

anonymous

Best ResponseYou've already chosen the best response.0Yes, Area = 48 cm^2, but that is just one part, we have a lot many parts to do..

Best ResponseYou've already chosen the best response.0Just leave this step for a while, now we come to Perimeter...

Best ResponseYou've already chosen the best response.0What is Perimeter?? It is sum of all the side lengths a rectangle has...

Best ResponseYou've already chosen the best response.0A rectangle has two length sides and two width sides, yes or no?

Best ResponseYou've already chosen the best response.0I thought you went on speaking Japanese while learning rectangles. :P

anonymous

Best ResponseYou've already chosen the best response.0Okay, so add all the side lengths.. \(Perimeter = l + l + w + w = 2 l + 2w \)

anonymous

Best ResponseYou've already chosen the best response.0I don't understand the answer. I understand that we are going to be adding the lengths and widths together but what does that end result mean?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Nothing.. We are just adding all the lengths and widths we have.. Now, you try adding all sides of your original question..

anonymous

Best ResponseYou've already chosen the best response.0That is good.. Now this is exactly you are half way done..

Best ResponseYou've already chosen the best response.0Now, read your question last line or last few words, if your rectangle is ENLARGED BY SCALE FACTOR OF 5.5, Right?

anonymous

Best ResponseYou've already chosen the best response.0It means now your length and width both have been increased by 5.5 cm thereby enlarging it.. Getting this point?

anonymous

Best ResponseYou've already chosen the best response.0So, 8 has now become (8+5.5 = 13.5) and width has now become (6+5.5 = 11.5).. All good?

anonymous

Best ResponseYou've already chosen the best response.0yeah, so I will add 13.5 + 13.5 + 11.5 +11.5 , correct?

anonymous

Best ResponseYou've already chosen the best response.0So, now your rectangle becomes : dw:1437070820960:dw

Best ResponseYou've already chosen the best response.0Good yaar, you are faster than light now.. :) Yes add them to get your new Perimeter that you need to find..

anonymous

Best ResponseYou've already chosen the best response.0So C and D options are cancelled out.. Now find Area as you did earlier..

anonymous

Best ResponseYou've already chosen the best response.0Area = Length x Width... Just put the values in..

anonymous

Best ResponseYou've already chosen the best response.0Any mistake have you done?

anonymous

Best ResponseYou've already chosen the best response.0155.25 cm2 , I believe that's correct.

anonymous

Best ResponseYou've already chosen the best response.0No, it is all right.. Good, is your option B right??

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Sorry, I mean check values in option A again..

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Area there is 155.5 or 155.25, have you missed 2 there? I think yes, because your option C has 155.25, you must be missing 2 there..

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Both c and a have 155.25 as an option.

anonymous

Best ResponseYou've already chosen the best response.0That is good.. So, you go with A here , right??

anonymous

Best ResponseYou've already chosen the best response.0Okay, good but just go with A and then leave it, don't marry it and take to your home.. :P

anonymous

Best ResponseYou've already chosen the best response.0alright xD , thanks for the help.

anonymous

Best ResponseYou've already chosen the best response.0Any doubt anywhere??

anonymous

Best ResponseYou've already chosen the best response.0To summarize the formulae: \(1. \quad Area = Length \times Width\) \(2. \quad Perimeter = 2(Length + Width)\) In case of Rectangle only.. :)

anonymous

Best ResponseYou've already chosen the best response.0thank you so much I suck at math. Fanned you! :D
