Question

The width of a rectangle is 3/8 the length x of the rectangle. What is the perimeter of the rectangle?

Answer 1

(11/4)x units

Explanation:

for a rectangle,

perimeter = 2(length) + 2(width)

given:

length = x

width = (3/8)x

hence,

perimeter = 2(length) + 2(width)

perimeter = 2x + 2(3/8)x

perimeter = 2x + (3/4)x

perimeter = [2 + (3/4)]x

perimeter = (11/4)x
