Question

The altitudes to the sides AB and AD of parralelogram ABCD are 5 Cm and 20 CM respectively. Of the area of the parralelogram is 160 sq .cm , find its perimeter

Answer 1

Answer:

56 cm

Step-by-step explanation:

area of llgm= b*h

                 160=20*h

            160/20=h

                     8=h

now perimeter of llgm= 2(A+B)

                                    = 2(20+8)

                                     = 2*28

                                      = 56 CM
