Respuesta :

The formula for the area of a trapezoid is
  A = (1/2)(b₁ +b₂)h

Substitute the given information and evaluate. (Make sure all dimensions have the same units.)
  A = (1/2)(12 ft +5 ft)(8 ft)
  A = 68 ft²

The area of the trapezoid is 68 square feet.

Answer:

the area is 816

Step-by-step explanation:

Step-by-step

12 + 5 = 17

17 / 2 = 8.5
