Question

find the area of the triangle below. 15 in 4 in (triangle with base 15 in and height 4 in)

Explanation:

Step1: Recall triangle area formula

The area of a triangle is $\frac{1}{2} \times \text{base} \times \text{height}$

Step2: Substitute given values

Base $= 15$ in, Height $= 4$ in. Substitute into formula:
$\frac{1}{2} \times 15 \times 4$

Step3: Calculate the result

First compute $15 \times 4 = 60$, then $\frac{1}{2} \times 60 = 30$

Answer:

30 square inches
