What is the area on the bottom base? We have 9 m in the middle. We have 5 m and on top the length we had 3 m so what is the total area?

To calculate the total area of the trapezoid, we can use the formula for the area of a trapezoid:

Area = ((a + b) / 2) * h

Where:
a = length of the bottom base = 5 m
b = length of the top base = 3 m
h = height = 9 m

Plugging in the values:
Area = ((5 + 3) / 2) * 9
Area = (8 / 2) * 9
Area = 4 * 9
Area = 36 square meters

Therefore, the total area of the trapezoid is 36 square meters.
