Question

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

Explanation:

Step1: Recall the formula for the area of a triangle

The formula for the area of a triangle is $A = \frac{1}{2} \times base \times height$.

Step2: Identify the base and height

From the diagram, the base of the triangle is $20\ ft$ and the corresponding height is $5\ ft$.

Step3: Substitute the values into the formula

Substitute $base = 20$ and $height = 5$ into the formula: $A=\frac{1}{2}\times20\times5$.
First, calculate $\frac{1}{2}\times20 = 10$. Then, multiply $10\times5 = 50$.

Answer:

$50$ square feet (or $50\ ft^2$)
