HI,
*Note: the P of a rectangle is the sum of all 4 sides or is generaly written as:
2*l + 2*w = P and area is wrtten as l*w.
.
The question states the following to be true:
Let w represent the width
l = (w + 4)
.
2*(w + 4) + 2*w = 40yds
.
Simplify and solve for w
4w + 8 = 40yds
4w = 32yds
w= 8 yds
l = 12yds
.
A = l*w
