Question

An artist is designing a mural that will be 3 feet wider than it is tall. If the area of the mural is 108 square feet, what will be height of the mural?

Answer 1

The height of the mural is 9 feet.
Equation is set up as follows:

(x)(3 + x) = 108

Solved by completing the square, giving you two possible solutions: a negative or a positive number. In this scenario, it is not possible for the height to be negative, therefore the answer is 9.
