A rectangular bedroom floor has an area of 100 square feet and a length of 10 feet. What is the perimeter of the floor?

(1) Answers

The area is calculated by multiplying the length by width, the perimeter is calculated by adding up every side of the rectangle Considering that we already are given the length of the floor we must divide 100 (the area) by 10 (the length) to get the width 100/10= 10 (the width) The perimeter is equal to each side of the rectangle added together, a rectangle has two lengths and two widths Therefore: 10 (the length) + 10 (the length) + 10 (the width) + 10 (the width) = 40 The perimeter is 40 feet
