Question

Calculate the area of the figure. Round to the nearest tenth if necessary.*2 points

Answer 1

The area of the trapezium is calculated as follows:

$A=\frac{b_1+b_2}{2}\cdot h$

Where b1 and b2 are the lengths of the bases (the parallel sides) and h is the height (perpendicular to the bases).

The figure gives us: b1 = 16 yd, b2 = 20 yd, h = 10 yd. Substituting:

$A=\frac{16\text{ yd}+20\text{ yd}}{2}\cdot10\text{ yd}$

Calculating:

$\begin{gathered} A=18\text{ yd}\cdot10\text{ yd} \\ \\ \boxed{A=180\text{ }yd^2} \end{gathered}$

Answer: C) 180 yd^2
