The length of a rectangle is 5 metres less than twice the breadth. If the perimeter is 50
metres, find the length and breadth of the rectangle.
Let the breadth be x
Then length =
Perimeter = 50 metres
Length + breadth =
+ x = 25
3x -
= 25

QUESTION:-The length of a rectangle is 5 metres less than twice the breadth. If the perimeter is 50
metres, find the length and breadth of the rectangle.
SOLUTION:-Let the breadth be x
Then length =2x-5
Perimeter = 50 metres
2(Length + breadth) = 2(x+2x-5)
3x -5=25 [because we know that perimeter of a rectangle= 2(l+b), so 50/2=25]
3x =25+5
3x=30
X =30/3
breadth =10metres
length = 2x-5m
=2*10-5m
=15 metres
HOPE THIS HELPS!
