Question

The length of rectangular field is 2.5 times its breadth. If the perimeter of this field is 119m, find its length and breadth.

Answer 1

Step-by-step explanation:

Let the breadth be x

Therefore length is 2.5x

Perimeter of rectangle= 2(l+b)

119=2(2.5x+x)

119=2*3.5x

119=7x

119/7=x

17=x

i.e x=17

Breadth=x=17

Length =2.5*x

=2.5*17

=42.5
