Graphing Quadratic Equations in Two Variables · Review Exercise 160

Solve. Rounding answers to the nearest tenth.

A daycare facility is enclosing a rectangular area along the side of their building for the children to play outdoors. They need to maximize the area using 180 feet of fencing on three sides of the yard. The quadratic equation gives the area, , of the yard for the length, , of the building that will border the yard. Find the length of the building that should border the yard to maximize the area, and then find the maximum area.
