Question

Find the area (in square feet) of a trapezoid with height h and bases b_1 and b_2. h = 6 in b_1 = 9 in b_2 = 12 in The area is _ square feet

Answer 1

Area of the trapezoid = 90 square feet

Explanation:

Area of a trapezoid with bases b₁, b₂ and height h is given by the formula,

Area of a trapezoid =
`(1)/(2)(b_1+b_2)h`

By substituting the given values in the formula,

Area =
`(1)/(2)(6+9)12`

=
`(180)/(2)`

= 90 square feet

Therefore, area of the trapezoid = 90 square feet
