Answer:
3x - 5 = 16 ft
2x - 3 = 11 ft
15 - x = 8 ft
Step-by-step explanation:
To find the perimeter, add up all the side lengths. Solve for x then substitute the value to find the dimensions.
[tex]3x-5+2x-3+15-x=35\\\\4x+7=35\\\\4x=28\\\\x=7[/tex]
[tex]3x-5=3(7)-5=21-5=16\\\\2x-3=2(7)-3=14-3=11\\\\15-x=15-(7)=15-7=8[/tex]
