Question

What is the perimeter, P, of a rectangle that has a length of x + 5 and a width of y − 1?

Answer 1

P= 2x+2y+8

Explanation:

On every rectangle, there are 2 widths and 2 lengths. Since you know the values of the length (x+5) and the width (y-1), you can just plug in the numbers.

The perimeter of the rectangle is 2(x+5) +2(y-1)

To simplify this, we must distribute.

2x+10+2y-2

2x+2y+8
