the base of a triangle is 15 cm and height is 12 cm . the height of another triangle of double the area having the base 20 cm is :
explanation : area of triangle , a 1 = 1 / 2 ∗ base ∗ height = 1 / 2 ∗ 15 ∗ 12 = 90 cm 2 area of second triangle = 2 ∗ a 1 = 180 cm 2 1 / 2 ∗ 20 ∗ height = 180 = > height = 18 cm option c
divide(multiply(multiply(const_2, triangle_area(15, 12)), const_2), 20)
