Rectangle A is 8 cm long and 4 cm wide. Rectangle B is 4 cm long and 2 cm wide. What is the ratio of the area of rectangle A to rectangle B?

8x4=32
4x2=8
32:8
Is my answer correct?

Yes, but the ratio can be simplified.

32:8 = 4:1

Yes, your answer is correct. The ratio of the area of rectangle A to rectangle B is indeed 32:8, or simplified as 4:1.

To calculate the ratio of the areas, you first need to find the area of each rectangle by multiplying the length by the width. In the case of rectangle A, its length is 8 cm and its width is 4 cm, so the area is 8 cm × 4 cm = 32 cm². Similarly, for rectangle B, its length is 4 cm and its width is 2 cm, so the area is 4 cm × 2 cm = 8 cm².

Therefore, the ratio of the areas is 32 cm² : 8 cm², or simplified as 4:1.
