The answer is 151.4496 cm², which can be rounded to 151.45 cm².
The area of a trapezoid is calculated by adding the top and bottom bases together, dividing that sum by two, and then multiplying the height.
A=[tex] \frac{a+b}{2} [/tex]h
A=[tex] \frac{22.2 cm+8.52 cm}{2} [/tex]h
A=[tex] \frac{30.72}{2} [/tex]h
A=15.36 cm×9.86 cm
A=151.4496 cm²
