Triangles • If one side of a triangular piece of yard area is roughly one-third the perimeter,
the second side is roughly one-fifth the perimeter, and the third side is 7yards,
what is the perimeter of the triangle?

15m

Step-by-step explanation:

The third side = (2/3 - 1/5) of the perimeter = 7/15 of the perimeter = 7m

The first side is 1/3 (=5/15) of the perimeter = 5m

The second side is then 3m ( or 1/5=3/15 of the perimeter).

The triangle perimeter is 15 meters (=7 m+5m+3m)
