for square = side * 4
for rectangle = 2 (length + breadth)
for triangle = sum of all the sides
regular polygon = side * 5
regular hexagon = side * 6
in fact , if all the sides of any quadilateral are equal , then the perimeter of the figure will be the lenght of the side multiplied by the number of total sides in the figure
Perimeter = sum of lengths of sides.
the formula is 1side multiply by 3
The formula for finding the perimiter of a rectangle is add up all of its sides
The formula for finding out perimeters of shapes is length+length+height+height=perimeter or what else you can do is (lengthx2)+(heightx2)=PERIMETER
Perimeter = 4*n whereas n is the length of its side
The sum of its 4 sides
P=2l+2w
Add the four sides.
It is the sum of its 4 sides
add all the sides ???
The formula for the circumference of a circle is pi * diameter or (2 radius.)
V- m/d where V is volume, m is mass and d is density.
