Question

Find the perimeter of the rectangle
10x - 3
2x + 6

Answer 1

`24x+6`

Explanation:

We know that the perimeter of a rectangle's formula is
`2l + 2w = p`, where l is the length and w is the width - p is the perimeter. We know the length and width, so we can substitute into the equation.

`(2\cdot(10x-3)) + (2\cdot(2x+6))\\\\(20x-6) + (4x+12)`

We can now combine like terms to get
`24x + 6`.

Hope this helped!
