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?

Divide by 30.48 to convert cm to feet 123 cm =123/30.48 feet
If the original meterstick was broken into two pieces, and one piece is 54 cm long, then the other piece would be the total length of the meterstick (100 cm) minus the length of the first piece. Therefore, the length of the other piece would be 100 cm - 54 cm = 46 cm.

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
