-- Find the length of the triangle's base. -- Find the length of the triangle's height. -- Multiply the base by the height. -- One half of the product is the area.
To find the area of a triangle, use the formula A = 2 1 bh , where b is the base and h is the height. Measure the length of the base and the height, then substitute these values into the formula. For example, a triangle with a base of 6 cm and a height of 4 cm has an area of 12 square centimeters.
