If the side of an equilateral triangle is increased by 34%, then by what percentage will its area increase?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 79.56%.
Given:
If the side of an equilateral triangle is increased by 34%
As we know,
The area of an equilateral triangle = √3a2/4
According to the question;
The percentage increase in the area = 34 + 34 + (34 × 34)/100 = 79.56%
