Question

Find a completely simplified expression for the perimeter (2 ⋅ length + 2 ⋅width) of the blue rectangle:

Answer 1

Answer: 18x-12

Step-by-step explanation:

2(6x+2+3x-8)

2(9x-6)

18x-12

Answer 2

The perimeter of the shown rectangle is given by the equation:

P = 2*(6x + 2)*(3x - 8)

How to get the perimeter?

For a rectangle of length L and width W, the perimeter is:

P = 2*(L + W).

Here we have:

L = 6x + 2

W = 3x - 8

Replacing that in our equation, we get:

P = 2*(6x + 2)*(3x - 8)

So the perimeter is given by the above quadratic equation.
