Answer: The first side is 22 feet
The second side is 11 feet
The third side is = 16 feet
Explanation:
Let x represent the length of the second side of the triangle.
One side of a triangle is 2 times the second side. It means that the length of the first side of the triangle is 2x feet.
The third side is 5 feet longer than the second side. It means that the length of the third side of the triangle is (x + 5) feet
The formula for determining the perimeter of a triangle is expressed as
Perimeter = a + b + c
Where
a,b and c are the length of each side of the triangle. The perimeter of the given triangle is 49 feet. Therefore,
2x + x + x + 5 = 49
4x = 49 - 5
4x = 44
x = 44/4
x = 11
The first side is 11 × 2 = 22 feet
The third side 11 + 5 = 16 feet
