No; that's perimeter, or the distance around.
do you mean math equation? If you add a number to both sides of an equation you do not change it. That is called algebra
It means the distance around something. For polygons, just add the lengths of all the sides.
no add the sides of the area
Add
add the lengths of all the sides

ADD
add the sides?
find area of all sides then add them
Do you mean "perimeter" and "Area"? If so, if you are finding the perimeter of a figure, you take the lengths of all of the sides and add them up. If you are finding area, the method of which you find the area of the figure depends on what the figure is. For quadrilaterals, the formula is: A=lw.(Area=length times width) For triangles, the formula is: A=1/2lw. (Area=One half length times width)
