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

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

To calculate the perimeter of a rectangular room with an area of 100 ft² and a length of 10 feet, we find the width by dividing the area by the length, which also gives 10 feet. Using the formula for the perimeter of a rectangle, we determine that the perimeter is 40 feet.
To find the perimeter of a rectangular bedroom floor with an area of 100 ft² and a length of 10 feet, we need to determine the width of the room. We can use the formula for the area of a rectangle A = length × width, which can be rearranged to find the width (W): W = A ÷ length. Given that the area (A) is 100 ft² and the length is 10 feet, the width would be W = 100 ÷ 10 = 10 feet.
Next, the perimeter (P) of a rectangle is the sum of all its sides, calculated with the formula P = (2 × length) + (2 × width). Substituting the values we have: P = (2 × 10) + (2 × 10) = 20 + 20 = 40 feet.
Therefore, the perimeter of the bedroom floor is 40 feet.

The perimeter of the rectangular bedroom floor is 40 feet. This is calculated by first finding the width from the area and length, then using the width and length to find the perimeter. The formula for perimeter is added lengths and widths together twice each.
