Question

The area of a particular rectangle is exactly equal to its perimeter. If it's length is 4 meters long,

what is its width?

Can you please help me..Thank you!

Answer 1

4m

Explanation:

We can set the expressions of area and perimeter equal to each other. Denote length as 'L' and width as 'W'.

LW = 2(L+W)

substitute 4 for L

4W = 2(4+W)

now solve for W

4W = 8+2W

2W = 8

W = 4
