Question

The perimeter of a pool table is 30 feet. The table is twice as long as it is wide. What is the lenght c of the pool table? Write an equation to model the situation. Then solve the equation for c.

Answer 1

If the perimeter is 30
and the length is twice the width
c=length
w=width
2c=w
a pool table has 4 sides, the two adjacent sides will be equal so we only need to account for 1 of the widths and 1 of the lengths
meaning we only need to use half of the perimeter, or 15
if the length is twice as long as the width
the length would be 10
the width would be 5
there are two widths and 2 heights so the perimeter would correctly add up to 30 feet, proving you have the right answer
