Question

If sides of an equilateral triangle is double then the ratio of new triangle to given triangle is _____​

Answer 1

Answer:

If every side of an equilateral triangle is doubled, the area of the new triangle is k times the area of the old one.

Answer 2

area of equilateral Δ with side a = √3/4a²sq.units

after doubling the side, new area= √3/4(2a)²= √3/4 4a²

K × √3/4a²= 4 × √3/4a²

∴ K = 4 is correct answer
