Question

The perimeter of a square is represented by the expression 32x - 12.8 find the side length of the square.

Answer 1

Given:

Perimeter of a square =
`32x-12.8`

To find:

The side length of the square.

Solution:

We know that, the perimeter of the square is 4 times of its side length.

`P=4a`

Where, a is the side length.

Perimeter of a square =
`32x-12.8`

Now,

`4a=32x-12.8`

Divide both sides by 4.

`a=(32x-12.8)/(4)`

`a=(32x)/(4)-(12.8)/(4)`

`a=8x-3.2`

Therefore, the side length of the square is
`8x-3.2` units.
