Answer:
304 feet²
Step-by-step explanation:
Given three walls :
First wall : 8 feets high ; 14 inches long
Second wall : 8 feets high ; 14 inches long
Third wall : 8 feets high ; 10 feets long
Area = Length * height
Area = (8 * 14) = 112 ft²
Area = (8 * 14) = 112 ft²
Area = (8 * 10) = 80 ft²
Total area :
(112 + 112 + 80) ft²
= 304 feet²
