Maxwell's windows has an area of 1152 square inches. the height of the window is 1/2 of its length. what is the length and height of maxwell's window?

A) area = length * height
B) height = .5 * length

Substituting equation B into A
A) area = length * .5 * length
1,152 = length * .5 * length
 1,152 = .5*length^2
.5*length^2 -1,152 = 0
length = 48
height = 24

Double-Check
area = 48 * 24 = 1,152
