Answer:

The length of Fence will be 20 m.

Step-by-step explanation:

As per given question we have provided that :

Here's the required formula to find Fence (Diaognal) of rectangle :

$\longrightarrow{\pmb{\rm{d = \sqrt{ {(l)}^(2) + {(w)}^(2)}}}}$

Substituting all the given values in the formula to find the length of Fence :

$\longrightarrow{\sf{Fence = \sqrt{ {(l)}^(2) + {(w)}^(2)}}}$

$\longrightarrow{\sf{Fence = \sqrt{ {(16)}^(2) + {(12)}^(2)}}}$

${\longrightarrow{\sf{Fence = \sqrt{ {(16 * 16)}+ {(12 * 12)}}}}}$

${\longrightarrow{\sf{Fence = \sqrt{ {(256)}+ {(144)}}}}}$

${\longrightarrow{\sf{Fence = √(256+ 144)}}}$

${\longrightarrow{\sf{Fence = √(400)}}}$

${\longrightarrow{\sf{\underline{\underline{\red{Fence = 20 \: m}}}}}}$

Hence, the length of Fence will be 20 m.

$\rule{300}{2.5}$

Answer:

fence length is 20 cm

Explanation:

let fence be c

use Pythagoras theorem,

a² + b² = c²

here a is 12 cm and b is 16 cm

12² + 16² = c²

c = √12² + 16²

c = √400

c = 20
