Question

what is the area of the trapezoid? 12 cm 17 cm 15 cm 17 cm 28 cm square centimeters

Explanation:

Step1: Recall area formula

The area formula for a trapezoid is $A=\frac{(b_1 + b_2)h}{2}$, where $b_1$ and $b_2$ are the lengths of the parallel - sides and $h$ is the height.

Step2: Identify values

Here, $b_1 = 12$ cm, $b_2=28$ cm, and $h = 15$ cm.

Step3: Substitute values into formula

$A=\frac{(12 + 28)\times15}{2}=\frac{40\times15}{2}$.

Step4: Calculate

$\frac{40\times15}{2}=20\times15 = 300$ square centimeters.

Answer:

300
