Answer:
70
Step-by-step explanation:
the formula for area of a trapezoid is (a+b)/2*h, where a and b each equal a base and h represents height. the base measurements of this figure are 9 and 11, and the height is 7 inches. in the formula, that is (9+11)/2*7. first, 9+11 is 20, divided by 2 is 10. 10*7=70, so the area is 70 in^2.

Answer:
The statement is trrue.
Step-by-step explanation:
Given that,
The surface area of a rectangular prism = 2,280 square feet
Width, b =20 feet
Height, h = 15 feet
The formula for the surface area of a rectangular prism is given by :
![A=2(lb+bh+hl)](https://tex.z-dn.net/?f=A%3D2%28lb%2Bbh%2Bhl%29)
Where
l is the length of the prism
Substitute all the values,
![A=2(lb+bh+hl)\\\\2,280=2(20l+20\times 15+15l)\\\\1140=(20l+20\times 15+15l)\\\\1140=35l+300\\\\1140-300=35l\\\\35l=840\\\\l=24\ feet](https://tex.z-dn.net/?f=A%3D2%28lb%2Bbh%2Bhl%29%5C%5C%5C%5C2%2C280%3D2%2820l%2B20%5Ctimes%2015%2B15l%29%5C%5C%5C%5C1140%3D%2820l%2B20%5Ctimes%2015%2B15l%29%5C%5C%5C%5C1140%3D35l%2B300%5C%5C%5C%5C1140-300%3D35l%5C%5C%5C%5C35l%3D840%5C%5C%5C%5Cl%3D24%5C%20feet)
So, the length of the prism is equal to 24 feet.
