Question

Piper used 1/5 meter of ribbon to create a border around a triangle if each side of the triangle is the same length how much ribbon did Piper use for each side?

Answer 1

`(1)/(15)`

Explanation:

as said in the question that the triangle has three equal sides. i.e. this is an equilateral triangle. So,

let us consider one side of the triangle to be x . and 3x( x+x+x) should be equal to 1/5

`x+x+x = (1)/(5)\\3x=(1)/(5)\\x = (1)/(5) / 3\\x = (1)/(5) * (1)/(3)\\x = (1)/(15)`
