The front wall of your shed is in the shape of a trapezoid. the bottom measures 22 feet, the top measures 20 feet, and the height is 10 feet. calculate the area of the front wall of your shed.

The area of a trapezoid is given by the formula:
  A = (1/2)×(b₁ +b₂)×h
Substitute the given information and evaluate.
  A = (1/2)×(22 ft +20 ft)×(10 ft)
  A = (1/2)×(42 ft)×(10 ft)
  A = (21 ft)×(10 ft)
  A = 210 ft²

The area of the front wall of your shed is 210 ft².
