Question

The perimeters of a triangle is 19 feet. One side of the triangle is 3 times the second side. The third side is 4 feet longer than the second side. Find the kength of each side?

Answer 1

9 ft, 3 ft 7, ft

Explanation:

Perimeter = 19 ft

Let side 2 = x

Side 1 = 3x

Side 3 = x + 4

perimeter = 3x + x + x + 4 = 19

5x + 4 = 19

5x = 15

x = 3

Side 1: 3x = 3(9) = 9

Side 2: x = 3

Side 3: x + 4 = 3 + 4 = 7

Answer:

9 ft, 3 ft 7, ft
