Answer 1

Answer :-

→ Breadth of rectangle = 18 m .

Step-by-step explanation :-

Given :-

→ Perimeter of rectangle = 86 m .

→ Length of rectangle ( L ) = 25 m .

To find :-

→ Breadth of rectangle ( B ) .

Solution :-

We have,

°•° Perimeter of rectangle = 2( L + B ) .

==> 86 m = 2( 25 m + B ) .

==> 86m/2 = 25 m + B .

==> 43 m = 25 m + B .

==> 43 m - 25 m = B .

==> 18 m = B .

$\therefore$ B = 18 m .

Hence, breadth of rectangle is 18 m .

Answer 2

Answer :

Breadth = 18 m

Step By Step Explanation :

Given :

Perimeter of the field (p) = 86 m

Length of the field (l) = 25 m

Breadth of the field (b) = ?

By The Formula,

Perimeter of rectangular field = 86 m

⇒ 2 (l + b) = 86 m

⇒ 25 + b = 86/2 m

⇒ 25 + b = 43 m

⇒ b = (43 - 25) m

∴ b = 18 m

Hence, The required breadth of the rectangular field is 18 m.
