Solution:-
length of side of a square = 15m
Area of square = Side²
= (15)²m²
= 225m²
When the each side of square is increased by 4 m then,
15 + 4 = 19m
New length of the side of square is 19m
Area of new square = (19)² m²
= 361m²
So,
Increase in area of square is given by,
New area of square - previous area of square
361 - 225
=> 136m²
