The Perimiter Of A Rectangle Is 84 Feet. The Reaction Of The Length To Width is 5:1. Find The Area Of The Rectangle

Answer 1

Given:

Perimeter of rectangle = 84

Ratio of length to width = 5:1

(Assume Ratio not Reaction)

Find: Area of rectangle

SOLUTION:

L = Length

W = Width

5/1 = L/W

L = 5W

Perimeter = 2L + 2W

84 = 2L + 2W

84 = 2(5W) + 2W

84 = 10W + 2W

84 = 12W

7 = W

L = 5W

L = 5(7)

L = 35

Area = L*W

Area = 35 * 7

Area = 245 square feet
