Question

What is the perimeter, P, of a rectangle that has a length of x + 6 and a width of y − 1? P = x + y + 5 P = x + y − 7 P = 2x + 2y + 10 P = 2x + 2y − 10

Answer 1

P = 2x + 2y + 10

Step-by-step explanation:

Given the following data;

Length of rectangle = x + 6

Width of rectangle = y - 1

To find the perimeter of the rectangle;

Mathematically, the perimeter of a rectangle is given by the formula;

P = 2(L + W)

Where;

• P is the perimeter of a rectangle.
• L is the length of a rectangle.
• W is the width of a rectangle.

Substituting into the formula, we have;

P = 2(x + 6 + y - 1)

P = 2(x + y + 5)

P = 2x + 2y + 10
