Question

a farmers has a rectangular field length and breadth 250m and 170 m, respectively he wants to fence it 4 rounds of rope. what is total length of rope must use?

Answer 1

Answer:

The farmer has to cover three times the perimeter of that field.

Therefore, the total length of rope required is thrice its perimeter.

Perimeter of the field = 2 × (length + breadth)

= 2 × ( 250 m + 170 m)

= 2 × 420 m

= 840 m

Total length of rope required = 3 × 840 m = 2520 m

Answer 2

Given that,

• Length of the rectangular field is 250 m.
• Breadth of the rectangular field is 170 m.

And, we've to find out the total length of rope must use.

⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━⠀⠀⠀⠀⠀⠀

⠀⠀⠀⠀

$\star \ {\underline{\boxed{\sf{\pink{Perimeter = 2 \times (Length + Breadth)}}}}}$

⠀⠀⠀⠀

$:\implies\sf 2 \times (250 + 170) \\\\\\:\implies\sf 2 \times 420 \\\\\\:\implies{\underline{\boxed{\frak{\purple{\: 840 \: m\: }}}}}$

$\underline{\bigstar\:\boldsymbol{According \ to \ Question\::}}$

• Farmer wants to fence the rectangular field 4 rounds of the rope.

$:\implies\sf Length \ required = Total \ perimeter \times 4 \\\\\\:\implies\sf 4 \times 840 \\\\\\:\implies{\underline{\boxed{\frak{\purple{\: 3360 \: m\:}}}}}$

⠀⠀⠀⠀

$\therefore\:{\underline{\sf 3360 \ m \ long \ rope \ is \ required.}}$
