A. 4

B. 6

C. 8

D. 12

Answer 1

When the perimeter of the triangle is doubled, it is 24. The perimeter before it is doubled is therefore half of 24=12.

An equilateral triangle is a triangle with three equal sides.

Perimeter = 12
Number of sides of an equilateral triangle = 3

Can you find the length of each side?
