A=LW Start with the given equation.


%28pq%29%2F18=%284%2Fp%29W Plug in A=%28pq%29%2F18 and L=4%2Fp


%28%28pq%29%2F18%29p=cross%28p%29%284%2Fcross%28p%29%29W Multiply both sides by "p".


%28p%5E2q%29%2F18=4W Multiply


%28%28p%5E2q%29%2F18%29%281%2F4%29=cross%281%2F4%29%2Across%284%29W Multiply both sides by 1%2F4.


%28p%5E2q%29%2F72=W Multiply the fractions.


So the width is W=%28p%5E2q%29%2F72
