Question

Find the area of a trapezoid whose lengths of parallel sides (bases) are 8.2 inches and 11.8 inches and height (perpendicular distance between the two parallel sides) is 6 inches.

Answer 1

60 in²

Explanation:

You want the area of the trapezoid with b1 = 8.2 in, b2 = 11.8 in, h = 6 in.

Area formula

The area of the trapezoid is given by the formula ...

A = 1/2(b1 +b2)h

A = (1/2)(8.2 in + 11.8 in)(6 in) = 60 in²

The area of the trapezoid is 60 square inches.

Additional comment

A formula is evaluated by putting the values where the corresponding variables are, then doing the arithmetic. A good calculator can evaluate the expression as written in the formula. No intermediate calculations are required.
