The length of a rectangle is a 1 metre more then its breadth.its area is 3 square metre . what is the length and breadth

Answer»

Let breath of the rectangle be 'B'.
Then , LENGTH = b+1 ..... SINCE , given length is 1 meter more than BREADTH .
Area = LB
3 = b(b+1)
3= b^2+b
b^2 +b -3=0
By solving the equation , you will get b=+ -1+ √13)/2 or( -1-√13)/2
And length = -√13/2 or + √13/2
