Answer:
the largest area of the store is 3300 ft² ( square foot)
Step-by-step 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
