Trapezoid

Area of trapezoid = 1/2*b*(h_1 + h_2)

==> The area of the trapezoid is 105.

The height of a trapezoid is 8 cm. The lengths of the two diagonals of the trapezoid are 10 cm and 17 cm. Calculate the area of the trapezoid.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Since the type of trapezoid is not specified, we can use a right trapezoid.

AB = sqrt(BD² - AD²)

CD = sqrt(AC² - AD²)

Area       A = AD [(AB + CD) / 2]  ==>  A = 84 cm²
