How many inches will the ribbon be?

4 * √ 64 = 32 inches

find the side with the inverse formula of the Area ( if A = l², l = √A), then multiply by 4, you find the perimeter and your answer

x = 12

y = 15

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
