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.
