NEED HELP ASAP PLZ!!!

The perimeter of this rectangle can be calculated using the equation P = 2 × 18.5 + 2 × 7.2.

Which other equation could be used to calculate the perimeter?



A.P = (2 • 18.5) + 7.2

B.P = 2 × 18.5 × 7.2

C.P = 2 (18.5 + 7.2)

D.P = 2 × 18.5 + 7.2

Answer 1

PLZ HELP ME WILL GIVE MEDAL

Answer 2

The answer is D. Because (18.5*2)+(7.2*2) is equivalent to 2(18.5+7.2). To figure this out, figure out the solution to the given equation and then find the solutions to the ones listed. whichever one matches--that's your answer. Does that make sense?

Answer 3

Scratch that, C is the correct answer, not D.

Answer 4

The answer is C. You know the opposing sides are the same\[Area=2*18.5+2*7.2 = 2(18.5+7.2)\]

Answer 5

You know the opposite sides are the same so you also know that the sum of two of the sides are the same as the other sides so you can commonize and the result is the answer
