Question

The perimeter of a rectangular room is 60 feet. Let x 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.

2(x+y)=60
2x+2y=60
x+2y=60
2x+y=60
x+y=60

Answer 1

Explanation:

2(x+y)=60

2x+2y=60

The second is the same as the 1st but with the distribution

perimeter formula: P=2(W+L)

We can distribute .Then P = 2W+2L
