I think D.
They both rested for 2 minutes, however they did not rest at the same time, but it doesn't say they did that in the option choice.

Answer:
9/12
Step-by-step explanation:
You have to divide 36 by 4 to get 9 and then divide 48 by 4 and you will get 12.
2.8 multiplied by 2.8 to find the surface area of the base which is 7.84
4*1/2*2.8*5.5 to find the surface area of all four triangular faces which is 30.8
Plus them together 7.84 plus 30.8 which is 38.64
The answer is -12 because the 4 and 8 are negative
