Question

Find the length of the iron wire required to fence a ground whose length is 20m and breadth 15
m

Answer 1

2(l+b)

2(20+15)=2(35)=

70m. . Ans.

Answer 2

$\textbf{\underline{\underline{Answer :-}}}$

The Length of the wire needed to Fence the Rectangular ground is 70 m

$\textbf{\underline{\underline{Explanation :-}}}$

$\textsf{\underline{\underline{Given :}}}$

Length of the ground = 20m

Breadth of the ground = 15m

$\textsf{\underline{\underline{To find :}}}$

Length of the iron wire required to fence a ground.

$\textsf{\underline{\underline{Solution :}}}$

To get the Length of the wire needed, we need to find the Perimeter of the ground.

Perimeter of the Rectangle =

$\tt{\implies2(l + b)}$

$\tt{\implies2(20 + 15)}$

$\tt{\implies40 + 30}$

$\tt{\implies70}$

${\boxed{\tt{{\bigstar \: {Perimeter = 70m}}}}}$

$\therefore$The Length of the wire needed to Fence the Rectangular ground is 70 m

• Rectangle is a quadliateral which has opposite sides equal and all angles measuring 90°.

• Area of Rectangle = Length × Breadth
