Question

How do you find the area of a triangle when you are only given the base which is equal to 21cm​

Answer 1

If the base of the triangle is 21 cm and the height (H) is also given as 21 cm, you can calculate the area of the triangle using the formula:

Area = (base * height) / 2

Substituting the values:

Area = (21 cm * 21 cm) / 2

Area = (441 cm²) / 2

Area = 220.5 cm²

Therefore, the area of the triangle is 220.5 square centimeters.
