Question

the length of a rectangular field is 8 metres less than twice its breadth. If the perimeter of the rectangular field is 56metres,find its length and breadth?​

Answer 1

Answer:

length is 8 metres less than its breadth

let,breadth is x

then ,length=2x-8

• perimeter of rectangle=2(l+b)
• p=2(2x-8+x)
• p=2(3x-8)
• 56=6x-16
• 6x=56-16
• 6x=40
• x=20/3
• breadth is 20/3m
• length =2*20/3-8

l=40/3-8=16/3
