Question

find the perimeter of a rectangle whose length=22.5m and the breadth= 16 dm

Answer 1

Let length of Rectangle be L and Breadth be B
Now, According to Given question,

L = 22.5 m   and    B = 16 dm
 
We Know,      1 dm = 0.1 m
       Thus       16 dm = 16 * 0.1 m
                                 = 1.6 m
So,                
              Breadth,   B = 1.6 m

Thus as we know,                  Perimeter of Rectangle = 2 (L + B)
 So,                                        Perimeter = 2 (22.5 + 1.6)
                                                               = 2 * 24.1
                                                               = 48.2 m


Thus the perimeter of the rectangle is 48.2 m.
