A rectangular yard measuring 38 ft by 56 ft is bordered (and surrounded) by a fence. Inside, a walk that is 2 ft wide goes all the way along the fence. Find the area of this walk.​

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.

use a calculator or a graph

if your equation is in the form ax2 + bx + c, you can find the maximum by using the equation:

max = c - (b2 / 4a).

the first step is to determine whether your equation gives a maximum or minimum.

-x2 + 4x - 2.     thats an example hope it
