Question

Write a function rule for the area of a rectangle who’s the length is 3 feet more than it’s width what is the area of the rectangle when it’s width is 9 feet

Answer 1

A = 108 ft^2

Explanation:

W = width

Area of this rectangle when W = 9 ft is:

A = W * L = (9 ft)(9 ft + 3 ft) = (9 ft)(12 ft) = 108 ft^2
