By working out the area inside the 4 cm perimeter.
examples
If it is an equilateral triangle with 3 equal sides of 4cm then its perimeter is 12cm
Area = ~50.27 cm2
The area is 12 cm2.
24 cm
42 = 4 x 4 = 16 cm2
If it is an equilateral triangle with 3 equal sides of 4cm then its perimeter is 12cm
SA = 96 cm2
Area = ~50.27 cm2
27.53 cm2 approx.27.53 cm2 approx.27.53 cm2 approx.27.53 cm2 approx.
The perimeter of a square with an area of 169 cm2 is: 52 cm
The area is 12 cm2.
Area : 44cm² Perimeter : 30cm
Yes (apart from units):If the side of a square is 4cm then itsperimeter is 4cm + 4cm + 4cm + 4cm = 4 x 4cm = 16cm;area is 4cm x 4cm = 16cm2

A square with a perimeter of 24 cm has an area of: 36 cm2
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 .
