If every side of an equilateral triangle is doubled. then the area of new triangle becomes I: times the area of the old one. What is h equal to ?

A) \( \sqrt{3}\)
B) 2
C) 4
D) 8

Correct Answer:



C) 4

Description for Correct answer:
Area of equilateral triangle with side 'a' = \( \Large \frac{\sqrt{3}}{4}a^{2}\)

Now Area of new triangle with side '2a' = \( \Large \frac{\sqrt{3}}{4}(2a)^{2}\)

= = \( \Large \frac{\sqrt{3}}{4} \times 4a^{2}\)

=\( \Large \sqrt{3}a^{2} \)
