Any value up to 20.25 sq feet.Let B be any number less than or equal to 4.5 feet be the breadth of the rectangle, and let L = 9 - B feet be the length.Then perimeter = 2*(B + L) = 2*(B +9 - B) = 2*9 = 18 feet.Area = L*B so that whenB = 1, L = 8 and area = 8 sq ftB = 0.1, L = 8.9 and area = 0.89 sq ftB = 0.01, L = 8.99 and area = 0.0899 sq ftB = 0.001, L = 8.999 and area = 0.008999 sq ftAs this shows, the area can be made smaller and smaller, without affecting the perimeter.

12*18 sq ft = 216 sq ft

0.5*apothegm*perimeter = 0.5*3*20 = 30 sq feet

18 ft * 16 ft = 288 sq feet

If the room is 18 FEET by 19 feet, the area of the room is 18 feet * 19 feet = 18/3 yards * 19/3 yards = 18*19/9 sq yards = 2*19 sq yards = 38 sq yards.

The perimeter of a square with an area of 25 sq ft is 20 feet because each side of the square is 5 feet, so the perimeter must be 4 x 5 feet.

0.5*apothegm*perimeter = 0.5*3*20 = 30 sq feet

A perimeter is a measure of length and so it cannot have sq feet as units. There are precisely 5227 feet in a perimeter of 5227 feet!

Perimeter: 400 feet. Area: 1,000 sq. feet.

Any number greater than or equal to 46.49 feet. A circle with radius 7.4 feet (approx) is the smallest shape that has a perimeter of 46.49 feet and and area of 172 sq feet. A square with sides of 13.11 feet (approx) has an area of 172 sq feet. These shapes can be stretched and squashed so as to leave their areas unchanged (at 172 sq feet) but increase their perimeters without limit. eg a rectangle of length 17200 feet and width 0.01 feet will have a perimeter of 34400.02 feet a rectangle of length 17200000 feet and width 0.00001 feet will have a perimeter of 34400000.00002 feet

49 square feet.

18 ft * 16 ft = 288 sq feet

Information about the area is not enough to determine the perimeter. 640 acres is 1 sq mile. The smallest perimeter possible is if the area is in the shape of a circle and in that case the perimeter would be 3.54 miles = 18717 feet. If the area is a square the perimeter would be 4 miles = 21120 feet. If it is a rectangle, then any value greater than 4 miles.

If the room is 18 FEET by 19 feet, the area of the room is 18 feet * 19 feet = 18/3 yards * 19/3 yards = 18*19/9 sq yards = 2*19 sq yards = 38 sq yards.

Perimeter is 300 yards. This is a length and is not measured in square feet which measure area. The area of this in square feet is 150 x 300 ie 45000 sq ft
