Question

find the area.
area of a triangle:
$a = \frac{bh}{2}$
(the triangle has a base of 4 in, a height of 5 in, and a side of 6 in. $a = \boxed{?} \text{in}^2$)

Explanation:

Step1: Identify base and height

Base \( b = 4 \) in, height \( h = 5 \) in.

Step2: Apply triangle area formula

Substitute into \( A = \frac{bh}{2} \): \( A = \frac{4 \times 5}{2} \)

Step3: Calculate the value

\( \frac{20}{2} = 10 \)

Answer:

10
