Answer 2

The area of given trapezoid is 68.8 cm²

Explanation:

Given: A trapezoid with height 6.4 cm and parallel base is 12.9 cm and 8.6 cm.

We have to find the area of area of this trapezoid.

Area of trapezoid =
`(1)/(2)* \text{sum of parallel sides}* height`

Given : Height = 6.4 cm

and parallel base is 12.9 cm and 8.6 cm.

Substitute, we have,

Area of trapezoid =
`(1)/(2)* (12.9+8.6)* 6.4`

Simplify, we have,

Area of trapezoid =
`(1)/(2)* 21.5* 6.4`

Area of trapezoid = 68.8 cm²

Thus, The area of given trapezoid is 68.8 cm²
