The city ordinances for Toon Town require a 25' front setback, a 20' rear setback, and 15' side setbacks. Your property measures 100' length (depth) X 90' width (front of the lot). What is the largest square foot single story home you could build on this lot?

the largest area of the store is 3300 ft² (square foot)

Explanation:

since

- width has to diminish in both sides of the square by 15' → largest width is 90 - 2*15 = 60' = 60 ft

- length has to diminish in the front by 25 cm and 15 from the back of the store → largest length of the store is 100 - 25 - 20 = 55' = 55 ft

therefore the largest area of the store is

Maximum area = largest width * largest length = 60 ft * 55 ft = 3300 ft²
