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

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.

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
