Explanation

area of a triangle $$= \frac{1}{2}* B * H$$
$$B=$$ base of the triangle and $$H =$$ Height or Altitude of the triangle

Given, $$B = H$$ and Height $$= 2H$$

Area of the triangle $$= \frac{1}{2} * B * H = \frac{1}{2} * H * 2H$$
$$2$$ in the numerator and denominator cancel out leaving $$H * H = H^2$$
Option C

Remember to find the area of the triangle base can be any of the three sides however height of the triangle should be perpendicular to the base chosen
