Question 1043871
.
A 350m barbed fenced around the rectangular field, the length is 5 times more than its breadth find the dimension of its breadth
~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
L + B + L + B = 350,  (1)
L = 6B.               (2)

Simplify:

L + B = {{{350/2}}} = 175,   (1')
L = 6B.                (2')

Substitute (2') into (1'). You will get

7B = 175  --->  B = {{{175/7}}} = 25.

<U>Answer</U>.  The breadth is 25 m.
