The base of a triangle is 10 cm and height 6 cm. What will be the height of another triangle of double the area having the base 12 cm?

The base of a triangle is 10 cm and height 6 cm. What will be the height of another triangle of double the area having the base 12 cm? Correct Answer 10

Area of first triangle = (1 / 2) * b * h = (1 / 2) * 10 * 6 = 30cm2 Area of second triangle = 2 * area of first triangle = 2 * 30 = 60 cm2 ➩ 60 = (1 / 2) * b * h ➩ 60 = (1 / 2) * 12 * h ➩ 60 = 6 * h ➩ 60 / 6 = h ➩ 10 = h
