300cm ?30cm mesirment batam parimeter are area

Dear student
As your question is not saying properly, i am assuming that we are given with a rectangle of length 300cm and breadth 30cm, and we need to find area and perimeter.

Length = 300cm
Breadth = 30 cm
Perimeter = 2(length+breadth)
                   = 2(300+30)
                   =2×330
                   =660cm
Area = length×breadth
         =300×30
         =9000 cm ^2

If you have any other query, please ask again and be more specific so that we can provide you with some meaningful help!
Regards
