Question

4 ft
5 ft
what is the area of the triangle?
square feet

Explanation:

Step1: Recall triangle area formula

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

Step2: Substitute given values

Here, base $= 5$ ft, height $= 4$ ft. Substitute into the formula:
$\text{Area} = \frac{1}{2} \times 5 \times 4$

Step3: Calculate the result

First compute $5 \times 4 = 20$, then multiply by $\frac{1}{2}$:
$\text{Area} = \frac{1}{2} \times 20 = 10$

Answer:

10 square feet
