The area of a rectangle can be found by multiplying its length by the width. A square is a special type of rectangle which has sides of equal length. Therefore a square that is 8 cm long will also be 8 cm wide. To find the area of this paper, you would multiply the height (8) by the width (also 8) 8 cm x 8 cm = 64 cm2

1 m = 100 cm 1 sq m = 1 m x 1 m = 100 cm x 100 cm = 10000 sq cm ⇒ 0.01 sq m = 0.01 x 10000 sq cm = 100 sq cm A C7 envelope (big enough to hold a piece of A7 paper, or A6 paper folded in half, or A5 folded in quarters) is 8.3 cm by 11.2 cm which has an area of 8.3 cm x 11.2 cm = 92.2 sq cm. It should be quite possible to write your name and address on a piece of paper with an area of 0.01 sq m = 100 sq cm, for example a piece of paper 10 cm by 10 cm. Now that I've written my name and address on a piece of paper 10 cm by 10 cm, what should I do with it?

To convert mm to cm: Divide the given length in mm by 10. Example: Convert 123 mm to cm: = 123 mm * 1cm/10 mm = 123 cm/10 = 12.3 cm To convert cm to m: Divide the given length in cm by 100. Example: Convert 123 cm to m: = 123 cm * 1m/100 cm = 123 m/100 = 1.23 m To convert mm to m: Divide the given length in mm by 1000. Example: Convert 123 mm to m: = 123 mm * 1cm/10 mm * 1m/100 cm = 123 m/1000 = 0.123 m
