Question

The length of a rectangle is 6 yd more
than 3 times its width. Find the length
and the area of the rectangle given that
its perimeter is 44 yd.

Answer 1

the area of the rectangle is 72 yd^2. the length is represented by 3w+6. the perimeter equation is 2l+2w, so you would plug in 2(3w+6)+2w=44. once you solve that, w=4. plug in 4 into 3w+6 and you would get 18 for the length. area is lw, so 18(4) is 72
