Answer:
just do 7 times 1/4 + the 12 thats your answer
Step-by-step explanation:
John exercised 20% more than Toby. So the number of hours that John exercises per week is 14 + 0.2(14) = 14 + 2.8 = 16.8.

The diameter of the plate would be equal to the length of a side of the box.
Find the length of the box by dividing the perimeter by 4:
28 / 4 = 7 inches.
The diameter is 7 inches.
