The length of the floor is 5.5 meters because 2*(5.5+5) = 21 meters which is the perimeter
15
Let the width be 1/2x+20 and the length be x: 2(width+length) = perimeter 2(1/2x+20+x) = 520 ft x+40+2x = 520 x+2x = 520-40 3x = 480 x = 160 Therefore: width = 100 ft and length = 160 ft Check: 2(100+160) = 520 ft
lenght=15, width= 10
It is area, not perimeter!
The floor of a rectangular deck has an area of 600 sq. ft. The floor is 20 ft. wide. How long is the floor?45
If the room is rectangular - the usual case - multiply the length times the width. If length and width are in meters, the area will be in square meters; if length and width are in feet, the area will be in square feet, etc.
Assuming the floor is rectangular the perimeter is the distance around the whole floor. So 2.3 + 3.4 + 2.3 + 3.4 = 11.4 m
The closer you get to a perfect square, the smaller the perimeter. A 6x6 square will have a 24 perimeter. A 36x1 will have the largest perimeter. The area is the same, but the length has 'stretched' to cover a larger perimeter.
(7.3m x 4.2m) = 30.66 square meters
Total area is 37.8 m2

2l+2w=24 l=2w 2(2w)+2w=24 4w+2w=24 6w=24 w=4 l=2w=2*4=8 Length is 8 meters, the width (or breadth) is 4 meters.
Area = Length x Width The area of the dance floor will be 12x6=72 square metres
47' x 94'
Area = length x width 40 = length x 4.5 length = 40/4.5 = 8.8888 meter
Bumper cars ride with 24 square meters of floor space and 22 meters of rail section.
