Step-by-step explanation:
✏let length and width will be x and y.
[ we know area of rectangle ]
area = length × width .
✏ But, a/c to questions .
↪length increase by 50%
= x + (x/2)
= 3x/2
↪ Width increase by 20%
= y +( y/5)
= 6y/5
✏So,new area of Rectangle will be
area = (3x/2)(6y/5)
= xy(3×6)/(2×5)
= xy ( 9/5)
= (1.8)xy
⏩Thus:-
↪ Area 1.8 time will be increases.
