Question 898207: it says on my h.w paper thatt use x2 on a calculator and theres a square drawn on my paper and on one side its 18cm and on the other side it says 18cm and the other two side dont have a number written next to it so can i know what the square root is of that Answer by Theo(13342) (Show Source):
You can put this solution on YOUR website! the convention is to show the measurement of one of the horizontal sides and one of the vertical sides under the assumption the side opposite each is the same.
if you want to find the area then you multiply 18cm * 18cm to get 324 square cm.
if you want to find the perimeter than you add up 2 * 18 cm and 2 * 18 cm to get 72 cm.
the horizontal side is usually called the length.
the vertical side is usually called the width.
sometimes the convention is that the length is usually the longer side.
in that case, you would call the longer side the length and the shorter side the width.
the sides opposite are always equal in lgneth to each other if the figure is a square or a rectangle or a paralellogram.
if really doesn't matter which side is called the length or which side is called the width.
this is because the area is equal to the length * the width which is the same as the width * the length.
this is also because the perimter is equal to 2 * the length + 2 * the width which is the same as 2 * the width + 2 * the length.
