The perimeter of the rectangle is 20cm.if the length of rectangle is 6cm,then its breadth will be
Answers
Answer:
To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the totallength for the remaining 2 sides. This number divided by 2 is the width.

Answer:
As we know the perimeter of rectangle = 2(l + b)units. (let length be l ; breadth be b)
On further simplification we get (2 l +2 b) units
Given: Perimeter = 20 cm ; length = 6 cm ; breadth = ?
Answer :
2(l) + 2(b) = 20 cm
2(6) + 2 b = 20 ( the value of length is given in the question .So i substituted the value of l with 6 )
12 + 2 b = 20
2 b = 20 - 12 ( by transposing method)
2 b = 8
b = 4 cm
So we have found the breadth value.
Verification :
2(l + b) = 20
2 (6 + 4) = 20
2*10 = 20
20 = 20
L.H.S =R.H.S
Hence verified
I hope i have clarified your doubts and this will be helpful to you
