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

Respuesta :

A square has 4 equal sides so the perimeter is:-

4(4,8x + 2.4)

= 19.2x + 9.6

= 8(2.4x + 1.2) The answer is C.

Answer:

Option C. 8( 2.4x + 1.2 )

Step-by-step explanation:

Length of the sides of a square is given by the expression ( 4.8x + 2.4 )

Then we have to find the expression that represents the perimeter of the given square.

Since perimeter of a square = 4 × ( side of the square )

                                              = 4( 4.8x + 2.4 )

                                               = 8( 2.4x + 1.2 )

Therefore, option C. 8(2.4x + 1.2) represents the perimeter of the square.
