Can someone explain how to find the area of a triangle

The area of each triangle is one-half the area of the rectangle. So, the area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle.

12.5 units²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = bh ( b is the base and h the perpendicular height )

Here b = 5 and h = 5 , thus

A = 0.5 × 5 × 5 = 0.5 × 25 = 12.5 units²
