Question

The length of the sides of a square is given by the expression 4.8x + 2.4. Which expression represents the perimeter of the square?

A.
4.8x + 2.4 + 4
B.
19.2x + 2.4
C.
8(2.4x + 1.2)
D.
4.8x + 9.6

Answer 1

C. 8(2.4x + 1.2)

Explanation:

Usually the answer would be 4(4.8x + 2.4) but there is no option for that, although there is c which is technically

4 (2) (2.4x + 1.2) because you're dividing the expression into a half.
