Given the statement:

Brett painted three walls. Each wall was 9 ft tall and 12 ft long.

Determine the area of the wall.

Solution:

Let us assume that the wall is rectangular in shape since we are given the length and the width, now in order to find the area of wall we must add 9 3 times as well as 12 since we have 3 walls.

Total Width= 9 + 9 + 9 

Total Width =27 ft 

Total Length = 12 + 12 + 12

Total Length = 36 ft

Formula for the area of a rectangle:

A = lw

Substitute the given values of  length and width to the formula for the area of the rectangle.

A = (27ft)(36ft)

A = 972 ft^2

Final answer:

A = 972 ft^2
