Question

Never have done the area of a trapezoid. I need help

Answer 1

`A = h( (b_1+b_2)/(2))` is a very complicated way of saying: "add the two bases together then half that number then times by the height."

For the trapezoid in your question:
Add the bases: 125 + 81 = 206
Half it: 206 ÷ 2 = 103
Times by height: 103 × 75 = 7725 sq ft
