Question

the perimeter of a rectanguar field is400m.If its length is 120m.then find its breadth?​

Answer 1

Answer:

please mark me as BRAINLIEST as well as give me a LIKE !!

Step-by-step explanation:

perimeter of rectangle = 2(l+b)

400=2(120+B )

(120+b) = 400/2 = 200

breadth = 200–120

breadth = 80 m

Answer 2

To find : breadth of rectangular field .

Given :  perimeter of a rectangular field is $400$ m. Length is $120\ m$ .

Solution :

• According to question we are given that perimeter and length of rectangular field is $400$ m and $120\ m$ respectively. We have to find breadth of field.
• To find breadth we use following formula -

       Perimeter of rectangular field = $2 (l + b)$

• Substituting the values we get,

      $400 =2 ( 120 + b )\ m\\200 = (120 +b )\ m \\b = (200 -120)\ m \\b = 80\ m$

Hence, breadth of rectangular field is $80\ m$ .
