Example 6: The perimeter of a rectangle is
100 m. If its length is increased by 10% and
the breadth remains the same, the perimeter is
increased by 6%. Find the length and the breadth
of the rectangle.​

Answer 1

Answer:

Given that 2(l+b)= 100

2(110/100l+b) = 106

110/100l+b = 53

110l+100b =5300

10l+100*50=5300

10l=300

I=30

Then b= 20

Therefore length and breadth of the rectangle are 30m and 20m
