Ans. 9/5 times

Solution-
Let be the length of a rectangle field = X
And breadth of a rectangle field     = Y
Area of rectangle    =X
50% of length = X x 50/100 = X/2
New length is    = X + X/2  = 3X/2
20% of breadth = Y x 20/100 = Y/5
New breadth is = Y + Y/5 = 6Y/5
New Area of rectangle = 3X/2 x 6Y/5
=  9/5 XY
