Question

in a parallelogram ABCD AB = 9.5 cm and its perimeter equals to 30 cm so find the length of its of each side of parallelogram

Answer 1

Hi user!

We know opposite sides of a parallelogram are equal.
That means that two sides are equal to 9.5 cm and let other two be equal to x.

Perimeter of a polygon= sum of its sides
              30                  =9.5+9.5+x+x
              30                  =19.0+2x
          30-19                 =2x
           11/2                   =x
           5.5                     =x

Thus sides will be 9.5,
                             9.5,
                             5.5,
                             5.5
