"Crown Molding' is a decorative strip of wood around the walls up by the ceiling of a room. How many linear feet of crown molding will Kentaro need for the 4 walls of his rectangular bedroom, which is 12 feet by 10 feet?
Answers:
a.) 44 feet b.) 48 feet
c.) 60 feet d.) 120 feet
12+12+10+10 = 44
To find the amount of crown molding needed for the four walls of Kentaro's rectangular bedroom, we need to calculate the perimeter of the room. The perimeter is the sum of all the sides of the rectangle. In this case, we have a rectangle with dimensions of 12 feet by 10 feet.
The formula to find the perimeter of a rectangle is:
Perimeter = 2 * (length + width)
For Kentaro's bedroom, the length is 12 feet and the width is 10 feet. Plugging these values into the formula, we get:
Perimeter = 2 * (12 + 10)
Perimeter = 2 * 22
Perimeter = 44 feet
Therefore, Kentaro will need 44 feet of crown molding for the four walls of his rectangular bedroom.
So, the correct answer is a.) 44 feet.
