find the perimeter of the polygon with vertices A (-1,5) ,B (-1,-4),C (-6,-4), and D (-6,5)

Answer 1

Hi Saad,

we could either do this problem one of two ways . First, do the distance formula which is the square root of the sum of the square of the differences of the x and y coordinates. Or

map them on a coordinate graph. Try that Saad and you will see that they are vertical and horizontal lines and you can count the squares in the grid , add them up and you get the perimeter which is the sum of the lengths and widths together.

hope this helps
