A circle, radius 10/pi has an area of pi x 10/pi x 10/pi ie 100pi/pi2 ie 100/pi ie 31.8;
A square 5 to the side has an area of 25.
Even if you knew how many sides the polygon has, you stillcould not calculate its perimeter with that much information.Examples:-- An equilateral triangle with area of 20 has perimeter of 20.3885 .-- A square with area of 20 has perimeter of 17.889(rounded).-- A rectangle with area of 20 can have any perimeter more than 17.889 .4 by 5 . . . . area = 20, perimeter = 182 by 10 . . . area = 20, perimeter = 241 by 20 . . . area = 20, perimeter = 42..etc.
The perimeter and area don't depend on each other. Knowing one doesn't tell you the other. -- A circle with perimeter (circumference) of 20 cm has area of 31.83 cm2. -- A square with perimeter of 20 cm has area of 25 cm2 . -- A (9 x 1) rectangle has perimeter of 20 cm and area of 9 cm2 . -- A (8 x 2) rectangle has perimeter of 20 cm and area of 16 cm2 . -- A (7 x 3) rectangle has perimeter of 20 cm and area of 21 cm2 . -- A (6 x 4) rectangle has perimeter of 20 cm and area of 24 cm2 .
The perimeter is 20 cm
A square with an area of 20 acres has a perimeter of about 3,733.5 feet.
Lateral Area=Perimeter of the base * height perimeter=20 height=6 so, Lateral Area=20 * 6 Lateral Area=120cm
Area of square 400 so dimensions 20 x 20 making perimeter 80
circle
Perimeter and area are not sufficient to determine the shape of a figure.
Area = 25
the p/a ratio is the sum of the perimeter divided by the area therefore if perimeter is 20m and the area 25m2 the sum is 20/25=0.8
The area of square is : 400.0
The area of square is : 400.0
