Question

one formula for the area of a triangle is $a = \frac{1}{2} \cdot b \cdot h$.
the variable $b$ represents the length of the base of the triangle and $h$ represents its height.
what is the area of this triangle?

Explanation:

Step1: Determine the base and height

From the grid, the base \( b = 4 \) units and the height \( h = 4 \) units.

Step2: Substitute into the area formula

Using \( A=\frac{1}{2}\cdot b\cdot h \), substitute \( b = 4 \) and \( h = 4 \):
\( A=\frac{1}{2}\times4\times4 \)

Step3: Calculate the value

First, \( 4\times4 = 16 \), then \( \frac{1}{2}\times16=8 \)

Answer:

\( 8 \)
