Question

The area is 30 cm². What is the height of the triangle if the base is 4 cm.

Answer 1

Hello John,

Formula for the area of a triangle: A = base x height/2

area = 30 cm2, base = 4 cm so:

30 = 4 x height/2

multiply both sides by 2: 30 x 2 = 4 x height

60 = 4 x height

divide both sides by 4: 60/4 = height

therefore: 15 = height

The height of the triangle is 15 cm
