If it has an area of 81 square units it could be 1 unit x 81 units giving a perimeter of 2 x (1 + 81) = 164 units;
It could be 3 units by 27 units giving a perimeter of 2 x (3 + 27) = 60 units;
There are many other possibilities, most with non-whole number lengths of the sides.
The perimeter doesn't tell you the area. There are an infinite number of differentareas that it could have.-- If it's a circle with a perimeter of 36, then the area is 103.1324. (rounded)-- If it's a square with a perimeter of 36, then the area is 81 .-- If it's a rectangle with a perimeter of 36, then the area can be any numberthat's more than zero and less than 81 .
Perimeter is 36 feet.
Its area is 81 square inches.
For a square Area = Side2 thus Side = √Area = √81 = 9cmFor a square, Perimeter = 4 x Side = 4 x 9 = 36cm
If the area is 81 square feet what is the perimeter?
81 square feet.
3*27 = 81 and 3+3+27+27 = a perimeter of 60 inches
Length = 9 Width = 9 Your rectangle is a square.

If it was a square, the answer would be 81 square cm. The area will be the product of two numbers whose sum is half the perimeter.
No. Perimeter does not uniquely define surface area. Example: Perimeter = 36 If it's a square with sides = 9, then area = 92 = 81 If it's a rectangle measuring 12 by 6, then area = 72 If it's a rectangle measuring 15 by 3, then area = 45 If it's a rectangle measuring 16 by 2, then area = 32 etc. etc. etc. Each of these figures has the same perimeter, but they all have different areas.
4.5*18 = 81 and 4.5+4.5+18+18 = a perimeter of 45 inches 3*27 = 81 and 3+3+27+27 = a perimeter of 60 inches
If you restrict yourself to integers, it could be 36, 60 or 164 in. If it was a square, it would have to be 36.
The circle has the greater area. For a perimeter/circumference of 36 metres, Area of circle = 103.13 sq metres (approx) Area of 9*9 square = 81 sq metres Area of an L*(18-L) rectangle (L < 9 metres) = anything between 0 and 81 sq metres.
The perimeter of a rectangle gives only a maximum for the area, there is no minimum because the rectangle can be an infinitesimally thin but long rectangle with an area as small as you like. The maximum area is attained when the rectangle is, in fact, a square. So perimeter 12 => max area = 3*3 = 9 square units. and perimeter 18 => max area = 4.5*4.5 = 20.25 sq units. So the two can have the same area for any value in the range (0, 9]. You say 2? Smaller rectangle = 0.3542 * 5.6458 and the larger = 0.2300 * 8.7720 If you want an area of S square units then smaller rectangle = 0.5*[6-sqrt(36-2*S)] by 0.5*[6+sqrt(36-2*S)] and larger rectangle = 0.5*[9-sqrt(81-2*S)] by 0.5*[9+sqrt(81-2*S)]
