Area of a Triangle Together they make a rectangle. The area of each triangle is half of the area of the rectangle. This gives us a formula for the area of a triangle. Area = ½ base X height

Area of a Triangle Example Find the area of a triangle with base 4 cm and height 5 cm 5 Area = ½ base X height 4 Area = ½ x4 x 5 Area = ½ x 20 Area = 10 cm²

Area of a Triangle Example Find the area of a triangle with base 5 cm and height 12 cm 12 Area = ½ base X height 5 Area = ½ x 5 x 12 Area = ½ x 60 Area = 30 cm²
