The perimeter of a rectangle is 162 ft. The lenght is 3 more than twice the width. How do you find the dimensions of the rectangle?
1 Answer
Width:
Length:
Explanation:
Let the length be
Let the width be
l = 2w + 3
2(l+w) = 162
2w + 3 + w = 162/2
3w + 3 =81
3w = 78
w = "26 ft"
This means that
l = 2w + 3
l = 2(26) + 3
l = "55 ft"
