Answer 1

$\huge\bold{ANSWER:-}$

Let the breadth of the rectangular field be 'b' metres

Length of the rectangular field=25 m

Given,

Perimeter of the rectangular field= 86 m

=> 2(l+b)= 86

=> 2(25+b)= 86

$= > 25 + b = \frac{86}{2}$

$= > 25 + b = 43$

$= > b = 43 - 25$

$= > b = 18$

Therefore,

➡️ Breadth of the rectangular field is 18m
