Area of rectangular shed = 24* 25

Given Shed covers 5% of total lot => 5/100 * Area of total lot = area of shed
=> Area of total lot = 24*25 * (100/5) = 12000

(D) 22,500
(E) 30,000

Area of the shed:
24 ft * 25 ft = 600 sq ft
Shed's area is 5 percent of the lot

Area of lot L in square feet?

600 = .05L
$$(\frac{100}{5})$$ (600) = L
L = 12,000

The area of the shed is 25 x 24 = 600; thus:

600 = 0.05(lot)

600/0.05 = lot

12,000 = lot
