Question

Find the area of the trapezoid.4 in4 in.5 inA=in 2

Answer 1

To determine the area of the trapezoid we need to use the following expression:

`A=(B+b)/(2)\cdot h`

Applying the dimmensions given in the problem we can calculate the area as shown below:

`A=(5+4)/(2)\cdot4=(9)/(2)\cdot4=(36)/(2)=18\text{ square inches}`

The area of the trapezoid is 18 square inches.
