An equilateral triangle has the same perimeter as a square whose side is 12.What is the length of each side of the triangle?

Perimeter for rectangle/square is (length + width) x 2

12 + 12 = 24

24 x 2 = 48

So the perimeter is 48

divide 48 by 3 so it is split between 3 sides

48/3=16

so each side has a length of 16

Perimeter for triangle is adding up all the sides together

16 + 16 + 16 = 48 so the perimeter is the same as the square

16 is the answer

Hope this helps
