area of a rectangle gets reduced by 9 square units if its length is reduced by 5 units and breadth is increased by 3 if we increase the length by 3 units and breadth by 2 units the area is increased by 67 square units find the length and breadth of the rectangle

Answer» LET LENGTH of rectangle be x
and breadth be y
(l - 5)(b + 3) = lb - 9
lb + 3l - 5b - 15 = lb - 9

3l - 5b = - 9 + 15
3l - 5b = 6.......(i)
(l + 3)(b + 2) = lb + 67
lb + 2l + 3b + 6 = lb + 67
2l + 3b = 67 - 6
2l + 3b = 61.......(ii)
solved both equation, you GET your ANSWER
