Each side is 2cm
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 area is about 41.57cm2
