Question

height of parallelogram is 3dm if the area is 240cm² find the base of parallelogram

Answer 1

Height = 3dm = 30cm
Area = 240cm sq

Area = Breadth * Height

Breadth = Area / Height
              = 240/30
              = 8cm

Hope this helps you............

Answer 2

let base =x
Area=Breadth*Height
=x*3dm=240cm square
=x*30cm=24cm square
x=240/30
=8cm
