Question

the perimeter of a rectangular field is 120 m . if the length is 35 m, find its breathe.

Answer 1

☆ Solution ☆

Given :-

• The perimeter of a rectangular field is 120 m.

• The length of a rectangular field is 35 m.

To Find :-

• The breadth of the rectangular field.

Step-by-Step-Explaination :-

Let,

• The breadth of the rectangular field be b.

Now,

As we know that :-

Perimeter of rectangle = 2 ( length + breadth )

Where,

• The perimeter of a rectangular field = 120 m

• The length of a rectangular field = 35 m

• The breadth of a rectangular field = b

Putting the respective value,

120 = 2 ( 35 + b )

120 = 70 + 2b

2b = 120 - 70

2b = 50

b = 50/2

b = 25

Hence,

The breadth of the rectangular field is 25 m .

Answer 2

Given :-

• Perimeter of Field = 120m
• Length of Field = 35m

To Find :-

• Breadth of Field

Solution :-

➞ Perimeter of Field = 2 (L + B)

➞ 120 = 2 (35 + B)

➞ 120 / 2 = 35 + Breadth

➞ 60 = 35 + Breadth

➞ 60 - 35 = Breadth

➞ 25 = Breadth

________________

Verification :

⟾ Perimeter of Field = 2 (L + B)

⟾ Perimeter of Field = 2 (35 + 25)

⟾ Perimeter of Field = 2 × 60

⟾ 120 = 120

Hence Verified

Thus Breadth of Field is 25m
