Answer:
270 ft^2
Step-by-step explanation:
find the area of each side
top: 13x7=91
triangle shaped sides(both together): 12x5=60
tiny vertical side: 7x5=35
bottom: 12x7=84
add them all together to get the total surface area is 270ft^2
Hope this helps! :)
45 because, the short side is half of the big size. That might be correct. But I'm almost positive
