Question

1. find the perimeter. what type of triangle is this? 6.7 km 6.7 km 6.7 km

Explanation:

Step1: Calculate the perimeter

The perimeter \(P\) of a triangle is the sum of its side lengths. Given all sides \(a = b = c=6.7\) km.
\(P=a + b + c\)
Substitute \(a = b = c = 6.7\) km into the formula:
\(P=6.7+6.7 + 6.7=3\times6.7\)
\(P = 20.1\) km

Step2: Determine the type of triangle

A triangle with all three sides equal is an equilateral triangle. Since \(a=b = c=6.7\) km, this is an equilateral triangle.

Answer:

The perimeter is \(20.1\) km and the triangle is an equilateral triangle.
