Question

jennifer is stitching a tablecloth in the shape of a trapezoid. her blueprint for the table cloth is shown below. what is the area of the table cloth? a. 42 square feet b. 24 square feet c. 21 square feet d. 46 square feet

Explanation:

Step1: Recall 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: Identify values from the problem

Here, $a = 6$ feet, $b = 8$ feet, and $h=3$ feet.

Step3: Substitute values into the formula

$A=\frac{(6 + 8)\times3}{2}=\frac{14\times3}{2}=\frac{42}{2}=21$ square feet.

Answer:

C. 21 square feet
