Final answer:
The equation for the perimeter of a rectangle with width x and length y is 2x + 2y. In this case, the equation would be 2x + 2y = 118.
Step-by-step explanation:
To write an equation for the perimeter of the rabbit cage, we need to add up the lengths of all four sides. The bottom of the rabbit cage is a rectangle, so opposite sides have the same length. The equation for the perimeter of a rectangle is P = 2x + 2y, where x is the width and y is the length of the rectangle. In this case, since the bottom of the cage is a rectangle with a perimeter of 118 inches, the equation becomes 2x + 2y = 118.
