Perimeter is taking the length of each side and adding them together. Therefore, if you have the lengths as fractions, you find the common denominator and add the fractions normally.
you can only find the perimeter of shapes, honey, not fractions.
just find a common denominator and add like you regularly would with fractions.
If you know the perimeter, there is no need to find it again.
To find the perimeter you add and to find the area we multiply.
perimeter of what quadrant?
The perimeter of a triangle is the distance around it. Add the lengths of the three sides to find the perimeter.
You multiply the fractions
what is the perimeter of a pentegon?
Find the distance of each side and add to find the total perimeter.
You find perimeter by adding all the sides of a figure.
There is no reason for the perimeter of a triangle to have any relation to the perimeter of an unrelated rectangle!
There is no way to find perimeter from a 3D figure. However, you can find the perimeter of a side of a triangular prism by using perimeter formulas for a parallelogram or triangle.
