I think it's wrong but I tried....

Answer 2

Answer:

84m

Step-by-step explanation:

Given data about a triangle is :-

One side is 37m

2nd side is 12m

Third side is not given.

(3rd side)^2 = (37)^2 - (12)^2

(3rd side)^2 = 1369 - 144

(3rd side)^2 = 1225

3rd side = √1225

3rd side = 35

Perimeter of triangle = 37+12+35

Perimeter of triangle = 84m.
