Question

The length of a rectangle is three times the width. The perimeter of the rectangle is 40 inches. What is the area of the rectangle (in square inches)?

Answer 1

Answer: 75 square

Explanation:

Width is X

Length is 3x

Every rectangle has 2 equal widths x 2 equal lengths

Perimeter is 2x + 2(3x) = 40
X = 5

Width is now 5in

Length is now 15in

Area is 75in^2

Half of a perimeter is length + width, which equals to 20in

4x = 20, CX = 5
= 75 sq
