Perimeter of rectangle: 2*(20+15) = 70m
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
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.
