Step-by-step explanation:
perp. -5
y + 7 = -5(x - 4)
y + 7 = -5x + 20
y = -5x + 13
The top and bottom have area (2.4 ft)² = 5.76 ft².
The sides have area (4*2.4 ft)*(3.4 ft) = 32.64 ft².
The the total area is (2*5.76 +32.64) ft² = 44.16 ft². All but the bottom area is then 44.16 ft² -5.76 ft² = 38.40 ft².
The ratio (all but bottom area)/(total area) is then
38.40/44.16 ≈ 87.0%
