Answer:

Length = 8x - 3.2

Step-by-step explanation:

Perimeter = 4(Length)   [Since it's a square so all the sides are equal]

Given that Perimeter = 32x - 12.8

32x - 12.8 = 4(Length)

Dividing both sides by 4

=> Length = \frac{4(8x-3.2)}{4}

=> Length = 8x - 3.2

<u><em>Now, Three equivalent expressions to find the perimeter</em></u>

=> Perimeter = 32x - 12.8

=> Perimeter = 4(8x - 3.2)   [Perimeter = 4 (Length)]

=> Perimeter = 2(16x - 6.4)

Answer:

\boxed{8x-3.2}

Step-by-step explanation:

The perimeter is 32x - 12.8 of a square.

Use formula for perimeter of a square.

P=4a

P=perimeter\\a=side \: length

32x - 12.8=4a

Solve for side length.

\frac{32x - 12.8}{4} =a

8x-3.2=a

Three equivalent expressions for perimeter:

32x - 12.8

⇒ 8(4x - 1.6)

⇒ 4(8x - 3.2)

⇒ 2(16x - 6.4)
