Answer 1

`180 {m}^(2)`

Explanation:

The area of a trapezoid is given by:

`Area = (1)/(2) (sum \: of \: bases) * h`

From the diagram, the bases are 17m 23m, and the the height is 12m.

We substitute the values into the formula to get:

`Area = (1)/(2) (17 + 13) * 12`

`Area = (1)/(2) * 30 * 12`

`Area = 6 * 30`

This implies that

`Area = 180 {m}^(2)`
