Question

The width of a rectangle is 3 yards less than its length. The perimeter is 130 yards. Find the length and width of the rectangle.

Answer 1

2(L-3)+2L=130
2L-6+2L=130
4L=136
L=34 W =31

Answer 2

Length = 34 yards

Width = 31 yards

Explanation:

Perimeter = 2(l + w), where l = length, and w = width

We know that w, is l - 3

130 = 2(l + l - 3)

130 = 4l - 6

136 = 4l

l = 34

Width is 3 less than 34, or 31
