75.15%

- When the side of an equilateral triangle is increased by 34%, the new side becomes 1.34 times the old side.

- The area formula for an equilateral triangle is proportional to the square of its side, i.e., Area ? (side)\(^2\).

- New area/Old area = (1.34)\(^2\) = 1.7956

- So, percentage increase = (1.7956 - 1) x 100 = 79.56%

- Option 2, 79.56% is the correct answer.

- The other options (70.65%, 68.25%, 75.15%) are incorrect as they do not match this calculation.

- Therefore, the correct answer is option 2.
