Rhombus A has a base of 7 inches and an area of 35 square inches. Rhombus B has a base and height that are three times the base and height of rhombus A. Find the area of rhombus B and compare it to the area of rhombus A. Explain.

For rhombus A:

base = 7 in

area = 35 in²

Area of rhombus = b * h

⇒ 35 = 7 * h

⇒ h = 35/7

⇒ h = 5 in

Rhombus B:

height = 3*5 = 15 in

base = 7*3 = 21 in

Area = 15 * 21 = 315 in²

Area of rhombus B is 9 times area of rhombus A. When the dimensions are increased to 3 times the initial dimension, area became 9 times.
