Answer:
h = 20ft
Step-by-step explanation:
A = a+b/2 x h
Use the formula by substituting in the known measurements.
650 = 23 + 42 / 2 x h
Add the bases together. (23 + 42 = 65)
Divide by 2. (65/2 = 32.5)
Next, divide the area by the bases. (650/32.5 = 20)
There's your answer. The height is 20ft.
Remember, to check all you have to do is plug the numbers back into the formula.
(23 + 42 / 2 x 20 = ?) We already did the steps for the bases so all you have to do is multiply 32.5 by 20, which gives you 650.
Hope this helps.
