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.

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 = 2x

Given:Length of third side is 5 ft longer than the second side = 5+x

Perimeter 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,

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.

if x = 1, then the answer is 3.5
