Question

The length of a rectangle is twice its width. If the area of the retangle is 98 cm^2 (squared), find it's perimeter.

Answer 1

L = 2W
A = L*W
P = 2(L+W)

You can find the values of the dimensions of the rectangle, and subsequently the perimeter, if you use the above equations :-D

Answer 2

ok, but what has me confused is the "twice it's width" thing. I don't get these at all.

Answer 3

It's just saying that if you multiply the width of the rectangle by two, you get the length of the rectangle :)
