Best ResponseYou've already chosen the best response.1We are given L and W are the dimensions of the rectangle where L stands for length of the rectangle and W stands for width of the rectangle. We are also given by the first sentence that L is 2+3W or L=2+3W We are also given the the sum of the sides equals 100 meters>can you write this as a mathematical equation?

Best ResponseYou've already chosen the best response.1L+W+L+W <this is suppose to be 100 L+W+L+W is the perimeter of the rectangle (this is just the sum of all the sides) L+W+L+W=100 combine like terms on the left hand side.

freckles

Best ResponseYou've already chosen the best response.1I mean get w by itself

freckles

Best ResponseYou've already chosen the best response.1you are going to do to subtract both sides by a number to first isolate 8w then you will need to divide both sides by a number to isolate finally the w part

Best ResponseYou've already chosen the best response.1you could do that except it wouldn't isolate the 8w part

freckles

Best ResponseYou've already chosen the best response.1"The length of a rectangle is 2 more than 3 times the width. If the perimeter is 100 meters, what is the width of the rectangle? " This was the question you posted. Do you think you are done? (hint: don't forget the unit part of your answer)

freckles

Best ResponseYou've already chosen the best response.1well your question only asked to find the width which you sort of already did you just need the units part but if you wanted to find length (and here you will also need to put the units): but L=2+3w where we found w to be 12 so L=2+3(12)=2+38 L=38

freckles

Best ResponseYou've already chosen the best response.1do you remember what units were used in the question?

freckles

Best ResponseYou've already chosen the best response.1actually I put 38 instead od 36 and 2+36=38
