the side lengths of a triangle are increased by 50% to make a similar triangle. does the area increase by 50% as well? explain.
The area of a triangle; A = a * h / 2 If we want to increase all sides by 50% we will have the sides of a similar triangle: a1 = 1.5 a, b1 = 1.5 b, c1 = 1.5 c. Also h1 = 1.5 h And the new area is: A1 = 1.5 a * 1.5 h / 2 = 2.25 a * h / 2 = 2.25 A Therefore the area is increased by 125%. Answer: False.
