what is the area of a right triangle 9 centimeters high with a base of 9 centimeters

The formula to find the area of a right triangle is:

Area = 1/2 * base * height

Plugging in the values given:

Area = 1/2 * 9 cm * 9 cm
Area = 1/2 * 81 cm^2
Area = 40.5 cm^2

Therefore, the area of the right triangle is 40.5 square centimeters.
