Just tell me what you can't read!
First , divide the figure into 2 rectangles like this: |dw:1336004731947:dw| Got it so far?
Yeah so first I divide it and time 60 x 20?
Nope. divide it, you'll get this: |dw:1336004909711:dw|
So I would do 60 - 20?
Sure you need to do that :)
Ok after that then what do I do (: or is that it?
Now, calculate the area for the rectangle and the square :| Can you do it?
Hmmm, I'm not sure man I'm sorry
|dw:1336005217546:dw| How do the shaded part first. How do you calculate the area for that?
Would you cut it in to pieces?
I don't want to cut it anymore, Cutting once is enough for this question :/
Hmm ok after cutting it onces would that make half of ten 5?
Nope!!! I've cut it once already!!! Should i demonstrate how to do it?
Yes I'm sorry lol
You're sorry but you laugh... interesting :\ Now consider the shaded area, you can apply the formula Area = width x length , Since it is a rectangle. So Area of the shaded part, let's call it A1, = (60-20) x 10 = 40 x10 = ... Understand?
Yes so that would be the formula and what I would do?
That's the formula for calculating area of rectangle. you need to calculate area of the A1 and A2, then add them up. That'd be the area you want for answer PS |dw:1336005747609:dw|
Ok give me a min and I will tell ya what I come up with
Would 400m be the answer?
Nope, 400 is only for A2 /A1 lol You need to add A1 and A2 together :)
So would I add 400M +400M = 800M??
Yes!!! but the unit is not M it's m^2
Kk, Can you help me with 2 more?
Sure if i can :) But have to go in 15~20 minutes :|
Oh ok, The next 2 involves the same only with a figure. Here it is (:|dw:1336104085008:dw|
Sorry... First cut it into 2 as you did. |dw:1336007029176:dw| Can you find x and y?
Would I add both numbers to find the x and y?
Well I'm not sure then can you help quick because I gotta go.
x =1 since it is a rectangle, that's the property of it. y = 7-1 =6
You need to go, so do I
Now, calculate the area of 2 rectangles. |dw:1336007524975:dw| A1 = 1 x 6 A2 = 6 x 4 like the previous one, do addition for the 2
