- A square handkerchief has a side of 2x + 3.
- So, it is given that the handkerchief is a square.
- So, in other words we have to find out the area of a square.
- We know, area of a square = side²
- Therefore, the area of the handkerchief
- = (2x + 3)²
- = (2x)² + 2(2x)(3) + (3)²
- = 4x² + 12x + 9
