Question

find the area of the triangle below. be sure to include the correct unit in your answer.

Explanation:

Step1: Recall area formula for triangle

The area formula for a triangle is $A=\frac{1}{2}bh$, where $b$ is the base and $h$ is the height.

Step2: Identify base and height

From the triangle, the base $b = 20$ yards and the height $h=21$ yards.

Step3: Substitute values into formula

$A=\frac{1}{2}\times20\times21$.
First, $\frac{1}{2}\times20 = 10$.
Then, $10\times21=210$.

Answer:

$210$ yd²
