Answer:
1375 inches^2
Explanation:
We can split this into two rectangles
The bottom one is 15 inches high by 75 inches long
The area is
A = l*w = 15*75 =1125 inches^2
The second rectangle is on top and is 10 inches high by 25 inches long
A = l*w = 10*25 =250 inches ^2
Add the two areas together to get the total area
A = 1125+250 =1375 inches^2
