The length of a rectangle is 4 times its width. If its width is 8, what is its length?

1. 12

2. 4

3. 16

4. 32

The correct answer is: 32

The length of a rectangle can be found by multiplying its width by its length. In this problem, we know that the length is 4 times the width. If the width is 8, then the length would be 8 x 4 = 32. Option A, 12, is incorrect because it shows a length that is only 3 times the width, not 4 times as stated in the problem. Option B, 4, is incorrect because it shows the length to be the same as the width. Option C, 16, is also incorrect because it shows the length to be only twice the width, not 4 times. In summary, the correct length for this rectangle is 32, as stated in option D.
