Question

The area of a rectangle get reduced by 9 square unit, if its length is reduced by 5 unit and the breadth is increased by 3unit if we increase the length by 3 unit and the breadth by 2 units, then the area is increased by 67 square unit. Find the length and the breadth of the rectangle

Answer 1

let A- area b-breadth l-length
A=lb
A-9=(l-5)(b+3)
A+67=(l+3)(b+2)
therefore u get equations
3l-5b=6
2l+3b=61
solve them  and
u will get l=17.944 and b=9.5

Answer 2
