The problem asks to find the area of three triangles, labelled a, b, and c. All dimensions are in centimeters.

1. Problem Description

The problem asks to find the area of three triangles, labelled a, b, and c. All dimensions are in centimeters.

2. Solution Steps

a. For triangle a, the base is 12 cm and the height is 5 cm. The area of a triangle is given by the formula:

$Area = \frac{1}{2} * base * height$

$Area = \frac{1}{2} * 12 * 5 = 30$

b. For triangle b, the base is 12 cm and the height is 8 cm. The area of a triangle is given by the formula:

$Area = \frac{1}{2} * base * height$

$Area = \frac{1}{2} * 12 * 8 = 48$

c. For triangle c, the base is 6 cm and the height is 6 cm. The area of a triangle is given by the formula:

$Area = \frac{1}{2} * base * height$

$Area = \frac{1}{2} * 6 * 6 = 18$

3. Final Answer

a. The area of triangle a is 30 $cm^2$.

b. The area of triangle b is 48 $cm^2$.

c. The area of triangle c is 18 $cm^2$.
