Question

a side of an equilateral triangle is 2/8 cm long. draw a picture that shows the triangle. what is the perimeter of the triangle?

Answer 1

We use P = 3 times (side of triangle), where  P is the perimeter of the triangle.

P = 3(2/8)cm
P = (3/1)(2/8) cm long 
P = (3/1)(1/4)
P = (3)(1)/(1)(4)
P = 3/4 = (Decimal: 0.75)


Hope this helps!
