Question

the perimeter of the triangle shown is 216 feet. find the length of each side.
x feet
2x feet
(6x - 9) feet
(type integers or decimals.)

Explanation:

Step1: Set up perimeter equation

$x + 2x+(6x - 9)=216$

Step2: Combine like - terms

$9x-9 = 216$

Step3: Add 9 to both sides

$9x=225$

Step4: Solve for x

$x = 25$

Step5: Find side lengths

$x=25$, $2x = 50$, $6x - 9=6\times25 - 9=141$

Answer:

25, 50, 141
