Question

If 258m long rope is required to surround three times rectangular field of length 25m,find the breath of the field​

Answer 1

Answer:

• Breadth of rectangular field is 18 m.

Step-by-step explanation:

GivEn:

• Length of rectangular field = 25 m
• Length of rope = 258 m

To find:

• Breadth of rectangular field?

Solution:

☯ Let breadth of rectangular field be x cm.

Now,

★ According to the Question:

• Length of rope required to surround three times rectangular field is 258 m.

Therefore,

➯ 3 × (Perimeter of Rectangular field) = 258 m

➯ 3 × (2(l + b)) = 258

➯ 3 × (2(25 + b)) = 258

➯ 2(25 + b) = 258/3

➯ 2(25 + b) = 86

➯ 25 + b = 86/2

➯ 25 + b = 43

➯ b = 43 - 25

➯ b = 18 m

∴ Hence, Breadth of rectangular field is 18 m.
