Each side is 2cm

A square with a side length of 2 cm has an area of 4 square cm

if you mean 4cm by 4cm square, then the area is 16cm2

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

length----8cm breadth---4cm

The length should be 6cm and the width is 4cm.

multiply the width by the length, e.g. 5cm= width, 4cm= length, 5x4= 20, 20cm squared

to work out the area of a sqaure it is the length of the side multiplied by another side. seing as the sides of a sqaure are all equal, is is the side of a square multiplied by itself. for example if the side of a square was 4cm the equation would be: 4cm x 4cm = 16cm^2 do not get this equation confused with the equation for a rectangle which is length multiplied by the width. (L x W)

the equation for area is area = length * width. area = 3cm*4cm. Area = 12cm^2

The area is about 41.57cm2

Area = Length x WidthArea = 4 x 44 x 4 = 16Area = 16 cm2

40cm2
