The perimeter of a plane figure is the length of its boundary. Thus the perimeter of a rectangle of length L and width W is 2L + 2W. The perimeter of a circle is the length of its circumference.

P_square=4L where L is the length of the side of the square.

Sum of lengths bounding the shape = 100 cm. Without information about the shape it is impossible to say anything further than that. In a very few exceptional cases, the length of individual sides can be determined as well as the area. But in order to do that it is necessary to know what equation is required. There is no THE equation. In the majorrity of cases, though, there is no direct relationship between the perimeter and the area or lengths of sides.

You can write equations for each of the two facts provided, then solve the equations. If you call the length "l", and the width "w", the facts are:3 more than...: w = 2l+3 perimeter: 2(l+w)=60 This is fairly easy to solve if you replace the first equation in the second (in the second equation, replace "w" by the expression that is on the right, in the first equation).

The perimeter of a rectangle = 2L + 2W So, from your problem we know that L = W + 27 Use this equation for the length and substitute in the perimeter equation, we get: 2(W+27) + 2W = 96 Now we rearrange and solve for W 2W + 54 + 2W = 96cm 4W + 54 -54 = 96 -54 4W = 42 W = 10.5cm, and using this value L = 10.5 + 27 = 37.5cm

There is not enough information here to solve this PERIMETER = 2L + 2W = 27 Thereare two unknowns and only one equation, so there are an infinite number of possibilities. You need more info, like the area, to solve this

It depends on the shape, but I'm assuming you mean a square or rectangle. If it is not this shape, edit the question. In this equation L=Length W=Width So, to get the perimeter, you would use this equation: 2L+2W= Perimeter
