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
P=2l+2w
It is the sum of its 4 sides
