What is the perimeter of a 25 foot wide by 30 foot long classroom?

Do rectangles with the same area of 30 feet have the same perimeter?
They can, but not necessarily. Let's say we have a rectangle of 5x6 and another of 1x30. The areas of both are 30 square feet, but their perimeters are different. Perimeter of 5x6: 5+5+6+6=22 feet Perimeter of 1x30: 1+1+30+30=62 feet There are many more examples of this.
If a rectangle is 45 feet long and 30 yards wide what is the perimeter in feet?
270 feet.
