If it is an equilateral triangle with 3 equal sides of 4cm then its perimeter is 12cm
Since all four sides are equal in a square, a square with an area of 4cm2 must be 2cm on each side. Therefore, the perimeter is 2cm x 4 = 8cm.
It is: 8*4 = 32 cm
32cm (8 sides x 4cm = 32cm)
Square side 3cm. Rectangle 2cm x 4cm. Equilateral triangle side 4cm.
