A triangle has an area of 72 and a base of 10 what is the height

The area of a triangle is A=1/2*b*h

So we have 72=1/2*10*h

72=5*h

14.4=h

So the height is 14.4 units

Hope this helped!

were is the equation

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
