Answer 1

$\Large{\underline{\underline{\mathfrak{\bf{Question}}}}}$

A rectangular field has length

200 m and breadth 160 m

Find the rate of fencing the field at the

rate of Rs. 50 per meter.

$\Large{\underline{\underline{\mathfrak{\bf{Solution}}}}}$

$\Large{\underline{\mathfrak{\bf{\pink{Given}}}}}$

• Length of rectangular field = 200 m
• Breadth of rectangular field = 160 m
• Rate of facing in the field is 50 ₹/m

$\Large{\underline{\mathfrak{\bf{\pink{Find}}}}}$

• Rate of facing total area of rectangular field .

$\Large{\underline{\underline{\mathfrak{\bf{Explanation}}}}}$

★ Area of rectangular field = (length)×(Breadth)

➠ Area of rectangular field = 200 × 160

➠ Area of rectangular field = 32,000 m²

But, spend mony in per meter = ₹ 50

So,

➠ Total spend mony in total rectangular field will be = 50 × 32,000

➠ Total spend mony in total rectangular field will be = ₹ 16,00,000 per meter .

Answer 2

Given

$\bold{Length \ of \ the \ rectangular \ field} = 200 \ m\\\bold{Breadth\ of \ the \ rectangular \ field} = 160 \ m$

$\boxed{\bold{Perimeter \ of \ the \ rectangle = 2(length + breadth)}}}$

$\implies 2(200+160)\\\implies 2(360)\\\implies 720 \ m$

$\bold{Cost \ per \ meter} = Rs. \ 50\\\bold{Cost \ for \ 720 \ meters} = 720 * 50$

                                    $=\boxed{\boxed{\bold{36000 \ m^{2} }}}$
