Answer: 91m

Step-by-step explanation:

We set three sides of the triangle equal to 2x,6x,7x; because there is the ratio 2:6:7, which x is a common factor of these three sides.

P = a + b + c

2x + 6x + 7x = 195

    15x = 195

        x = 13

7x suppose be the longest side of the triangle, we plug in 13 for x, then:

7x = 7(13) = 91 m
