Question

The length of a rectangular field is twice its breadth.The perimeter of the field is 60 m. What are it's dimensions

Answer 1

Let the breadth be x

So , length = 2x

Perimeter of rectangle = 2( l+b)

60m = 2 ( 2x + x)

60m= 2 ( 3x )

60m = 6x

60m/6 = x

10m = x

Breadth = 10m

Length = 20m
