If it is an equilateral triangle with 3 equal sides of 4cm then its perimeter is 12cm
Square side 3cm. Rectangle 2cm x 4cm. Equilateral triangle side 4cm.
It is an equilateral triangle
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
Perimeter of square = 4*length of side = 4*4cm = 16 cm.
