Question

find the area of the trapezoid shown below 9 19 18 21 23 question help: video post to forum submit question

Explanation:

Step1: Recall area formula

The area formula for a trapezoid is $A=\frac{1}{2}(b_1 + b_2)h$, where $b_1$ and $b_2$ are the lengths of the parallel - sides and $h$ is the height.

Step2: Identify values

Here, $b_1 = 9$, $b_2 = 23$, and $h = 18$.

Step3: Substitute values into formula

$A=\frac{1}{2}(9 + 23)\times18$.
First, calculate the sum inside the parentheses: $9+23 = 32$.
Then, multiply by $\frac{1}{2}$ and 18: $A=\frac{1}{2}\times32\times18=16\times18 = 288$.

Answer:

288
