Question

find the area of the right triangle.

Explanation:

Step1: Determine the base and height

From the grid, the base \( b = 8 \) units and the height \( h = 5 \) units.

Step2: Use the area formula for a right - triangle

The formula for the area of a triangle is \( A=\frac{1}{2}\times b\times h \). Substitute \( b = 8 \) and \( h = 5 \) into the formula: \( A=\frac{1}{2}\times8\times5 \).

Step3: Calculate the area

First, calculate \( 8\times5 = 40 \). Then, \( \frac{1}{2}\times40=20 \).

Answer:

\( 20 \) square units
