One side of a triangle is 2 times the second side. The third side is 5 ft longer than the second side. The perimeter of a triangle is 81 ft. Find the length of each side.

Answer:19 ft, 24 ft and 38 ft are the lengths of triangle.Step-by-step explanation:Let the length of second side be x.Now given:Given: Length of first side is 2 times length of second side = 2xGiven:Length of third side is 5 ft longer than the second side = 5+xPerimeter of triangle = 81 ft.Need to Calculate length of each side.Now we know that sum of all three sides of triangle is equal to perimeter of triangle.Hence,[tex]x+2x+5+x =81\\4x= 81-5\\4x=76\\x=19 ft[/tex]Also,2x= 2×19 =38 ft.5+x = 5+19 =24 ft.Hence,Length of first side  = 38 ft.Length of second side = 19 ft.Length of third side =24 ft.
