The length and width of a rectangle are increased by 20%, and the area of the rectangle is increased by () requirement: 1. The problem solving process is clear 2. Have ideas 3. Easy to understand

Let length a and width b be the area ab
When the length and width increase by 20%, the area is 1.44ab when the length is 1.2A and the width is 1.2b
So the area is increased by (1.44ab - AB) / AB = 44%
