Question

What happens to the area of a rectangle if you double the length of each of its four sides? How would you explain it, and what would the area of the new rectangle be?

Answer 1

Answer: Area of new rectangle 4xy

Step-by-step explanation:

let length and breadth of rectangle be x and y

so, area= length*breadth

=xy

new sides are 2x and 2y

area of new rectangle

= 2x* 2y

= 4xy

Here area of new rectangle is four times of original rectangle
