^How do I solve this?

Answer 1

Here is a page that can tell you how to calculate trapezoid area without the formulas,

but I'll help you with this one.

Answer 2

\[A= (\frac{ b1+b2 }{ 2 })h\]

Answer 3

The triangle on the right is a 30 60 90 triangle, so if the hypotenuse is 8, then the small line in the lower right equals 4.
The height of the triangle equals the hypotenuse times [(square root of 3) / 2]
height = 8 * 0.8660254038
height = 6.9282032303

Area of the triangle = (6.9282032303 * 4) / 2
Area of the triangle = 13.8564064606

Area of the rectangle = 6.9282032303 * 11
Area of the rectangle = 76.210235533

Trapezoid Area = Rectangle Are + Triangle Area = 76.210235533 + 13.8564064606

Answer 4

Or to use the trapezoid area formula,
The bottom base is 11 + 4 = 15 feet and the
top base is 11 feet
Area = [(base 1 + base 2) /2] * height
Area = [(11 + 15) /2] * 6.9282032303
Area = 13 * 6.9282032303 =

90.0666419936
