Question

what is the area? 7 mm 6 mm 4 mm

Explanation:

Step1: Identify the trapezoid area formula

The formula for the area of 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: Determine the values of $a$, $b$, and $h$

Here, $a = 4$ mm, $b = 7$ mm, and $h = 6$ mm.

Step3: Substitute the values into the formula

$A=\frac{(4 + 7)\times6}{2}=\frac{11\times6}{2}$.

Step4: Calculate the result

$\frac{11\times6}{2}=\frac{66}{2}=33$ $mm^{2}$.

Answer:

$33$ $mm^{2}$
