Answer:
-$300
cost = $900
Step-by-step explanation:
1200/4 = 300
1200-300 = 900
Lets say she cuts squares of x by x in length.
Area of bottom will be (20 - 2x)(11 - 2x) = 80 inches squared
220 - 40x - 22x + 4x^2 = 80
4x^2 - 62x + 140 = 0
x^2 - 15.5x + 35 = 0
Using quadratic equation;
you get x = 2.743753901 0r 12.7562461 inches
The length of the square cannot be more than 11 inches
So the only squares you can cut are:
2.743753901 inches by 2.743753901 inches squares.
