Answer:

Hence, the number is 5

Width=15 ft

Length=33 ft

Step-by-step explanation:

Let the number be x

Hence,

Width= 3x

Length = 8+5x

As we know that perimeter of a rectangle = 2( Length + Width)

Hence,

[tex]2(3x + 8 + 5x) = 96 \\ 2(8x + 8) = 96 \\ 8x + 8 = 48 \\ 8(x + 1) = 48 \\ x + 1 = 6 \\ x = 5[/tex]

Hence,

Width=15 ft

Length= 33 ft
