The area of triangle shaded on the diagram is equal to 3a/2 square units.

In Mathematics and Euclidean Geometry, the area of a triangle can be calculated by using the following mathematical equation (formula):

Area of triangle = 1/2 × b × h

Where:

  • b represent the base area.
  • h represent the height.

Based on the diagram, we can logically deduce the following:

base, b = a units.

height, h = 3 units.

By substituting the given side lengths into the formula for the area of a triangle, we have the following;

Area of triangle = 1/2 × b × h

Area of triangle = 1/2 × a × 3

Area of triangle = 3a/2 square units.
