The perimeter of a photograph is 30 inches. It is 6 inches wide. How long is it in inches

Question

I am Doing IXL and I don't know this

Answer 1

If the perimeter is 30 inches, that means the length of 4 sides added together is 30. If it is a rectangle and one side is 6, there is another side that is 6. So these 2 sides are 12 inches.

What do we have left?

30 - 12 = 18 The remaining 2 sides are 18 inches.

18/2 sides = 9 inches

Check: 6+6+9+9 = 30
