Question

A farmer has a rectangular field of length and breadth 120m and 70m respectively. He wants to fence it with 2 rounds of rope. What is the total length of rope he must use?​

write steps too please

Answer 1

Answer: perimeter of rectangular field is 2(190)=380m

Therefore for 2 rounds he want 380×2=760m

He need 760m of rope

Step-by-step explanation:

Answer 2

Given

• Breath= 120 m
• length= 70 m

To find

Length of rope required to fence the field in 2 rounds

Procedure

First we will find the perimeter of the rectangular field by the formula 2(L+B). The perimeter of the field will be the required rope to fence it in 1 round. To find the length of the rope required to fence the field will be 2 times the perimeter.

Let's do it !

Solution

$\mathtt{ \pink{Perimeter \: of \: rectangle = \: 2(L+B)}}$

$\mathtt{\implies Perimeter \: of \: rectangle = \: 2(70+120)}$

$\mathtt{\implies Perimeter \: of \: rectangle = \blue{380 cm}}$

Length of the rope required to fence the field in 2 rounds = 2 × perimeter

length of the rope required to fence the field in 2 rounds = 2 × 380 = 760 cm
