To find out how much tape Brandon will need to wrap 11 presents, we can set up a proportion using unit rates.

Since Brandon used 8 centimeters of tape to wrap 4 presents, we can say that the unit rate is 8 centimeters of tape per 4 presents.

To find the unit rate, we divide 8 by 4:
8 centimeters / 4 presents = 2 centimeters of tape per present.

So, the unit rate is 2 centimeters of tape per present.

To find out how much tape Brandon will need to wrap 11 presents, we can set up another proportion using the unit rate:

2 centimeters/tape per present = x centimeters of tape / 11 presents.

To solve for x, we can cross-multiply and divide:

x = 2 centimeters/tape * 11 presents / 1

x = 22 centimeters of tape.

Therefore, Brandon will need 22 centimeters of tape in all to wrap 11 presents.
