Rhombus A:
Area = 35 square inches
base = 7 inches
height = 5 inches
Rhombus B:
Area = 315 square inches
base = 21 inches (7 x 3)
height = 15 inches (5 x 3)
A = 21 x 15
The area of Rhombus B is 9 times bigger than the area of Rhombus A. The reason is that 2 dimensions were tripled, so x3 x3 = 9 times bigger.
