# How do you find the area of a right triangle?

We will write the formula to find the area of a right-angled triangle.

## Answer: Area of right triangle = 1 / 2 × perpendicular × adjacent

Let's see how we can find it.

**Explanation:**

Area of any triangle = 1 / 2 × base × height

In the case of the right-angled triangle, we have height = perpendicular.

Since we, need two of three sides in the triangle to calculate the area, one of them is perpendicular, and the other being the base or the adjacent side in the right-angled triangle.
