Question

the length of a field is 80 m if the peremeter of the field is 260 m find its breath​

Answer 1

Question:

the length of a field is 80 m if the peremeter of the field is 260 m find its breath.

Answer:

breadth = 40 cm

Step-by-step explanation:

•p=2(l+b)

•260=2(90+b)

•130=90+b

⇒b=40cm= breadth

Answer 2

Correct Question :

• The length of a field is 80m .If the perimeter of field is 260m then find its breadth

Answer :

• Breadth is 50m

Given :

• Length is 80m
• Perimeter is 260m

To find :

• Breadth

Solution :

Given that , length is 90m and perimeter is 260 then we have to find breadth

As we know that ,

• Perimeter = 2(l + b)

》 perimeter = 2(length + breadth)

》 260 = 2(80 + b)

》 260/2 = 80 + b

》 130 = 80 + b

》 b = 130 - 80

》 b = 50m

Hence , Breadth is 50m

Verification :

• Length is 80m
• Breadth is 50m

As we know that,

• Perimeter = 2(l + b)

》 2(80 + 50)

》2(130)

》 260

Hence verified
