Question

Find the length of each side of an equilateral triangle with a perimeter of 147kilometers.

Answer 1

Given:

Perimeter (P) of an equilateral triangle = 147 km.

Required:

To find the length of each side (s) of an equilateral triangle.

Step-by-step explanation:

The perimeter of an equilateral triangle is given by,

`P=3* s`

Substituting values, we get the length of each side (s) of an equilateral triangle (in km) as follows:

`\begin{gathered} P=3* s \\ \Rightarrow147=3* s \\ \Rightarrow s=(147)/(3) \\ \Rightarrow s=49 \end{gathered}`

Final Answer:

The length of each side (s) of an equilateral triangle (in km) is,

`s=49`
