Which equation can be used to find the perimeter P of the rectangle?

• 8 x 10 = P

• 8 + 10 = P

• 8 x 10 + 8 x 10 = P

• • 8 + 10 + 8 + 10 = P

Answer explanation

The correct equation to find the perimeter of a rectangle is to add all four sides together, so 8 + 10 + 8 + 10 = P. Therefore, the equation 8 + 10 + 8 + 10 = P is the right choice.
