The percentage increase in the area of a rectangle is 44% if each of its sides is increased by 20%.
<h3>What is a rectangle?</h3>
It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.
It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
New length = (120x/100) m
New breadth = (120y/100) m
New area = (6x/5 × 6y/5) m²
The difference between the original area = xy
new area 36xy/25
Percentage increase = (11xy/25 1/xy x 100)
= 44%
Thus, the percentage increase in the area of a rectangle is 44% if each of its sides is increased by 20%.
