What is the area of a triangle that is 3cm x 5cm

The area of a triangle is given by the formula: 1/2 * base * height.

In this case, the base of the triangle is 3 cm and the height is 5 cm.

Area = 1/2 * 3cm * 5cm
Area = 1/2 * 15cm
Area = 7.5 cm^2

Therefore, the area of the triangle is 7.5 square centimeters.
