The measurements of the three sides of a triangle are represented by the expressions 2x, 3x and 4x. If the perimeter of this tri
angle is 18 feet, find the measurement of all three sides.
1 answer:
Answer:
4, 6 and 8
Step-by-step explanation:
The perimeter is the sum of the lengths of the 3 sides, hence
2x + 3x + 4x = 18
9x = 18 ( divide both sides by 9 )
x = 2
The 3 sides have length
2x = 2 × 2 = 4
3x = 3 × 2 = 6
4x = 4 × 2 = 8
