Answer:
B. 22.5m^2
Step-by-step explanation:
To find the area of a trapezoid, you must use the formula:
1/2 × height × (base 1+ base 2)
1. 1/2 × 5m × (8+1)
2. 1/2 x 5m x (9)
3. Switch it around to make it easier to solve
5m × 9× 1/2 (We can do this because of the commutative property.)
4. 45m × 1/2 = 45 ÷ 2 = 22.5m^2
In the context of the problem, this means that the area of the trapezoid is 22.5m^2.
