Now when you know about the right-angled Triangle in detail, this is the time to calculate the area of Right Triangle. The area is always measured in square units and defined as the space occupied by the two-dimensional shape within boundaries. The area of a right triangle formula can be given as – We can find the area of this house-shape in three parts. 1. The square has an area of 4 × 4 = 16 square units. 2. Triangle 2 has perpendicular sides of 3 and 2 units, so its area is (1/2) × 2 × 3 = 3 square units. 3. Triangle 3 is the same shape and size as triangle 2, so its area is also 3 square units.
