Question

what is the area of the trapezoid? 4 cm 4 cm 3 cm 8 cm square centimeters

Explanation:

Step1: Recall area formula

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

Step2: Identify values

Here, $a = 4$ cm, $b = 8$ cm, and $h = 3$ cm.

Step3: Substitute values into formula

$A=\frac{(4 + 8)\times3}{2}=\frac{12\times3}{2}$.

Step4: Calculate result

$\frac{12\times3}{2}=\frac{36}{2}=18$ square centimeters.

Answer:

18
