Question

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

Answer 1

B. 98 cm2

Explanation:
Let the dimensions of rectangle B be x and y.
Therefore, the dimensions of rectangle A are 4x and 4y.

Area of rectangle A = 4x * 4y = 16xy
given, Area of rectangle A = 1568 cm2

Then, 16xy = 1568
=> xy = 98

Therefore, the area of rectangle B = xy = 98.

So, the correct answer is option B.
