Identify the area of the trapezoid.
Vlad1618 [11]

Option B: The area of the trapezoid is 157.5 m²

Explanation:

We need to determine the area of the trapezoid.

The area of the trapezoid can be determined by the formula,

Area=\frac{h}{2} (a+b)

where h is the height, a and b are the base of the trapezoid.

From the figure, it is obvious that a=14 , b=7 and h=15

Substituting these values in the formula, we have,

Area=\frac{15}{2} (14+7)

Simplifying the terms, we have,

Area=\frac{15}{2} (21)

Multiplying the terms in the numerator, we have,

Area=\frac{315}{2}

Dividing, we get,

Area= 157.5 \ m^2

Thus, the area of the trapezoid is 157.5 m²

Hence, Option B is the correct answer.
