The dimensions of rectangle A are four times the dimensions of rectangle B. The area of rectangle A is 1,568 cm2.
What is the area of rectangle B?
A.
49 cm2
B.
98 cm2
C.
196 cm2
D.
392 cm2
C. 196 cm2
Since the dimensions of rectangle A are four times the dimensions of rectangle B, and the area of rectangle A is 1,568 cm2, we know that the dimensions of rectangle A are 28 cm by 56 cm (4 x 7 cm and 4 x 14 cm).
Therefore, the area of rectangle B would be 7 cm by 14 cm, which equals 98 cm2.
