The dimensions of rectangle B are twice the dimensions of rectangle A. The area of rectangle A is 162 cm2.

What is the area of rectangle B?

Since the dimensions of rectangle B are twice that of rectangle A, the area of rectangle B will be four times the area of rectangle A.

Area of rectangle B = 4 * 162 cm2 = 648 cm2

Therefore, the area of rectangle B is 648 cm2.
