What’s the perimeter of the room?

Question

The rectangular room measures 224 square feet. One side of the room is 14 feet long. What is the perimeter of the room?

Answer 1

The perimeter P is the total length around the room. A is the area of the room. The room is rectangular.

The room has 2 sides, let's call the length x and the width y. Let x=14 ft

A=x*y

224 ft^2 = (14 ft) * y

y=224ft^2/14ft=16 ft

The perimeter is found by summing up all the sides of the rectangle. There are 2 sides with a length x and sides with a length y.

P=2x+2y

P=2*(14 ft)+2*(16 ft)=60 ft

The perimeter is 60 ft.
