No, you can not calculate an area if you know just the perimeter. For example, rectangle with sides of 10 and 20 would have a perimeter of 60 and an area of 200, but a square of sides 15 would have a perimeter of 60 and an area of 225. You need to know more details about the shape than just the perimeter.
Oh, what a happy little question! Let's think about shapes that could have a perimeter of 15 and an area of 16. One shape that comes to mind is a rectangle with dimensions 4 by 4. Another possibility is a square with sides of length 4. These shapes show us that there can be different ways to create beautiful combinations of perimeter and area.
2+2+15+15=34cm
The perimeter of a rectangle is calculated by adding the lengths of all its sides. In this case, the rectangle has two sides of length 20m and two sides of length 15m. Therefore, the perimeter would be 2(20m) + 2(15m) = 40m + 30m = 70m.
Perimeter = 24 and area = 27 . . . . . rectangle, 3 by 9 Perimeter = 32 and area = 15 . . . . . rectangle, 1 by 15
The area cannot be 15 feet since that is a measure of length, not area. In any case, information about the area cannot determine the perimeter; it can only put a lower limit on it. The perimeter can be anyhting from 15.49193 ft upwards. Consider the following rectangles, all with area = 15 square feet: a sqrt(15)*sqrt(15) rectangle will have a perimeter of 4*sqrt(15) = 15.49193 ft (approx). 1ft*15ft rectangle will have a perimeter of 32 feet 0.1ft*150ft rectangle: perimeter = 300.2 feet 0.01ft*1500ft rectangle: perimeter = 3000.02 ft 0.001ft*15000ft rectangle: perimeter = 30000.002 ft by now you should see that there is no upper limit to the perimeter.
A 5 by 3 rectangle
The dimensions of the rectangle are 2 units and 15 units
If it's a rectangle then:- Area = 15*12 = 180 square units Perimeter = 15+15+12+12 = 54 units of measurement
Perimeter: 150+15+150+15 = 330 feet Area: 150*15 = 2250 square feet
For example, a 1x15 rectangle and a 2x14 rectangle. They both have perimeter of 32, but they have areas of 15 and 28, respectively.
It is a 3 x 15 rectangle !
15 x 7
Perimeter= 2(l+b) =2*39 =78m = Area =l*b = =24*15 =360m

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.
