Question

The perimeter of a rectangular room is 60 feet Let 3 be the width of the room (in feet) and let y be the length of the room (in feet). Select all of the equations below that could model this situation

Answer 1

We have a rectangle with following measures:

Width = x

Length = y

Perimeter = 60 feet

Therefore,

x + x + y + y = 60

2x + 2y = 60

or x + y = 30

x = 30 - y

y = 30 - x
