16 cm
Area = (side)2 = 16 square centimeters Perimeter = 4 x side = 16 centimeters
If it is an equilateral triangle with 3 equal sides of 4m then its perimeter is 12cm
A square with a side length of 2cm has an area of 4cm2
The perimeter is the addition of the all the sides of the shape. For example if a rectangle has two sides which are 4cm and two sides which are 7cm, then the perimeter will be 4cm+4cm+7cm+7cm. The perimeter would therefore be 22cm. The area of a shape is gotten by multiplying the length and breadth of the shape. For example, in a rectangle witrh the same measurements above, the area will be 4cm x 7cm and that would 28cm. You have to use the square sign but I can't do that here.
