Question

the perimeter of a pool table is 30ft. it is twice as long as it is wide. what is the length of the pool table?

Answer 1

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
