What is the perimeter, P, of a rectangle that has a length of x 5 and a width of y − 1? P = 2x 2y 8 P = 2x 2y − 8 P = x y 4 P = x y 6.

Perimeter of a rectangle is double of sum of its length  and width. The perimeter P of the considered rectangle is: Option B:

Its the sum of length of the sides used to made the given figure.

For a rectangle, as its two sides are equal to its length and two other sides are equal to its width, thus, its perimeter is:

For the given case, it is already given that:

The length of the considered rectangle  = x + 5 units

The width of the considered rectangle  =  y - 1 units.

Thus, we get this rectangle's perimeter as:

Thus,  The perimeter P of the considered rectangle is: Option B:
