If the length and width of a rectangule garden plot were each increased by 20% , what would be the percent increase in the area of plot ? Correct Answer 20%

Let, Length of rectangle garden x and width of rectangle garden y. area = xy New length = x + 20/100x = 1.2x New width = y + 20/100 y = 1.2y New area = 1.2x × 1.2y = 1.44xy % increase in area = 1.44xy - xy /xy ×100% = 44%
