2*(length + width) = 54 feet.
12ft x 15ft = 180ft2
44 feet
I would assume it to be 42 ft depending if you are talking about the inside of the room or the outside perimeter
A 20 x 20 room will have a perimeter of 20 + 20 + 20 + 20 = 80.
Perimeter = 38 feet Area = 90 square feet
the perimeter is how long around it is, like my room is 15 ft around, so therefore my rooms perimeter is 15ft
15ft+12.5ftft+15ft+12.5ft=55ft P=55ft
72
12ft x 15ft = 180ft2
That's a total of 20 square yards.
how many square yards of carpet will they need for a dining room9ft and 12ft, a hall 3ft and 6ft, a living room 12f and 15ft
Dimensional analysis. 12ft x 15ft = 180 ft^2, or 180 square feet. 12 x 15= 180
This has multiple answers. If you divide the length, room two is 36' x 12', with perimeter of 96' and area of 432 sq. ft. If you divide the width, room two is 48' x 9', with perimeter of 114' and area of 432 sq. ft.
14 x 12 = 168.
156ft2
450
The perimeter doesn't tell you the dimensions. It doesn't even tell you the shape.
