if a classroom is 2400 square feet and the width is 60 feet, what is the perimeter of the room

Answer 1

To begin, we need to find the length of the classroom.

Since we are given the area and width of the room, let's start with the formula for area.

Area = length x width

Now we plug in the information we are already given and work backwards to find our length.

2400 = length x 60

First, we want to get length on a side by itself so let's divide both sides by 60.

2400/60 = length

40=length

Now that we have a value for length, we can plug in our numbers in the Perimeter formula

Perimeter = 2(length) + 2(width)

Perimeter = 2(40) + 2(60)

Perimeter = 80 + 120

Perimeter = 200

Remember, it is important to ALWAYS include a unit of measurement in your answer, so your final answer would be 200 ft.

Answer 2

2400/60= 40 which is the other side of the rectangle. So now you do (60*2) + (40*2) -> 120+80 = 200 ft
