Ierofanga [76]

Answer:

19.2x+96 units

Step-by-step explanation:

The perimeter of a square is 4 times the length of one side.

The length of the sides of a square is given by the expression 4.8x+24

To find the perimeter, we multiply this expression by 4.

Perimeter=4(4.8x+24)

We expand to obtain:

Perimeter=4*4.8x+4*24

This simplifies to:

Perimeter=19.2x+96

This is where you would use cross-multiplication.
Multiply the x with 16 and the 2 with 4.

16x = 8

Now divide everything by 16.
x = 0.5</span>
