The volume of a rectangular pyramid
Given a rectangular pyramid of width W, length L, and Height H, the volume is

We have to assume the pyramid given in the question has a square shape of length and width of L=34.5 feet and W = 34.5 feet, and a height of H=55 feet, thus the volume is:

Answer:
Area of trapezoid = 210 unit²
Step-by-step explanation:
Given:
Height = 12 unit
Parallel side a = 15
Parallel side b = 20
Find:
Area of trapezoid
Computation:
Area of trapezoid = [(a+b)/2]h
Area of trapezoid = [(15+20)/2]12
Area of trapezoid = 210 unit²
71/2 can also be written as 15/2, so divide 15/2 by 3/4. When you divide fractions you flip the second fraction and multiply it, so now it would be 15/2 X 4/3, so you would get 60/6 which is 10!
