Option B is correct. The required area of the triangle will be 1/2 x 9 x 12

The formula for calculating the area of a triangle is expressed as:

A = 1/2 * base * height

Given the following parameters

Base = 9 metres

Height (altitude) = 12metres

Substitute the given values into the formula as shown:

A = 1/2 * 9 * 12

Hence the required area of the triangle will be 1/2 x 9 x 12
