Answer = 10m and 7m

Answer 1

hey mate.
here's the solution

Answer 2

length = x

breadth = y

Area = xy

(x + 3) (y - 3) = xy - 18

xy - 3x + 3y - 9 = xy - 18

3x - 3y =  9  

x - y = 3    ................(1)

(x + 3) ( y +3) = xy + 60

xy + 3x + 3y + 9 = xy + 60

3x + 3y = 51  

x + y  = 17  ..................(2)

(1) + (2)

x - y + x + y = 3 + 17

2x = 20

x = 10

If x - y = 3

10 - y = 3

y = 7

Length = 10m

Breadth = 7m
