P = 27 mWe're asked to find the perimeter of the triangle with a side length of 9 meters.The formula for the perimeter is:[tex]\sf P=3a[/tex], where a = side length Substitute 9 for a:[tex]\sf P=3*9[/tex][tex]\sf P=27\:m[/tex]
If one side of an equalateral triangle is 9m what is its perimeter?P=27m
