What is the area in square centimeters of a triangle whose length is 9cm and height is 7cm?
The formula to calculate the area of a triangle is:
Area = (base * height) / 2
Given that the length is the base (9cm) and the height is 7cm, we can substitute these values into the formula:
Area = (9cm * 7cm) / 2 = 63cm²
Therefore, the area of the triangle is 63 square centimeters.
