509cm: (5m = 500cm) + 9cm = 590cm
14cm X 9cm is the smallest legal size for a letter.They have all the information for parcel and letter size on their site: http://www.canadapost.ca/cpo/mc/personal/productsservices/send/lettersdocuments.jsf
The length of the rectangle is 18cm. The width of the rectangle is 9cm.
18 square cm
To find the area of a rectangle, you multiply its length by its width. In this case, the length is 9cm and the width is 3cm. So, the area of the rectangle would be 9cm x 3cm = 27 square centimeters.
To find the area of a rectangle, you multiply the length by the width. In this case, the width is 7cm and the length is 9cm. So, the area would be 7cm x 9cm = 63 square centimeters.

How about a rectangle, parallelogram or a kite
15 cm Solved through Pythagoras' theorem.
63 cmPerimeter = 2 x (Length + Width) = 2 x (9cm + 7cm) = 2 x 16cm = 32cm
if you have a box that is 9cm long and 3cm wide then you would say width + length + width + length because the side opposite from 3cm is also 3cm and the side opposite 9cm is also 9cm. so you would add: 9cm+9cm+3cm+3cm = 24cm if you have a box that is 9cm long and 3cm wide then you would say width + length + width + length because the side opposite from 3cm is also 3cm and the side opposite 9cm is also 9cm. so you would add: 9cm+9cm+3cm+3cm = 24cm
An arbitrary large number is the answer for anyrectangle, up to that with a length of 9cm, and 0cm as the width will have a perimeter of 18cm.Similarly, any rectangle up to that with sides 0cm long, and a width of 9cm will have your 18cm perimeter.
Perimeter = 6cm + 6cm + 9cm + 9cm = 30cm
Area = 108cm2 Width = 12cm Length = 9cm
