If the sum of squares of length(l) and breadth(b) of a rectangle is 89 cm2 and its area is 40 cm2, then what is the area of a square having side equal to the breadth of rectangle(l>b)?
  • a)
    25 cm2
  • b)
    49 cm2
  • c)
    64 cm2
  • d)
    Other than above
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
If the sum of squares of length(l) and breadth(b) of a rectangle is 8...
Let length and breadth of rectangle are l and b respectively.
As per given, l2 + b2 = 89 cm2 and lb = 40 cm2
(l +b)2 = l2 + b2 +2lb = 89 + 80 = 169
l +b =13 cm
l = 13-b
As lb = 40
(13-b) x b =40
13b -b2 =40
b2 - 13b +40 = 0
b = 8 or 5
If b = 8, then l = 5 and if b = 5, then b = 8
as length is greater than breadth. So, b = 5.
Area of square having side equal to breadth of rectangle= 25 cm2.
