we know that

pool table will be in rectangular shape

let's assume

length is l

width is w

we are given

perimeter is 30ft


perimeter =2(l+w)


30 =2(l+w)

we have

twice as long as wide

it means

l=2w

so, we can plug it


30 =2(2w+w)


30 =6w


w =5

now, we can find l


l =2*5


l =10ft.............Answer
