Question

The square.
5x - 8
ЗХ
What the perimeter

Answer 1

For this case we have that by definition, the perimeter of a rectangle is given by:

`P = 2a + 2b`

Where:

a, b: They are the sides of the rectangle.

We have according to the data that:

`a = 5x-8\\b = 3x`

SUBSTITUTING:

`P = 2 (5x-8) +2 (3x)\\P = 10x-16 + 6x\\P = 16x-16`

Thus, the perimeter of the rectangle is:
`P = 16x-16`

Answer:

`P = 16x-16`
