A rectangle has a perimeter of 40 inches. It is 3 times as long as it is wide. What is the area of the rectangle in square inches?
The width of the rectangle is w, therefore the length is 3w. The perimeter, P, can then be described as P = w + w + 3w +3w 40 = 8w w = 5 width = 5, length = 3w = 15 A = 5 × 15 = 75 square inches
The width of the rectangle is w, therefore the length is 3w. The perimeter, P, can then be described as
P = w + w + 3w +3w
40 = 8w
w = 5
width = 5, length = 3w = 15
A = 5 × 15 = 75 square inches
