Question 993301
Area of walkway, {{{4*12=48}}} square feet
Area of 1 stone, {{{2*2=4}}} square feet


{{{(48*ft^2)/(Q*stones)=(4*ft^2)/(1*stone)}}}


{{{((48*ft^2)/(Q*stones))(Q*stones)=((4*ft^2)/(1*stone))(Q*stones)}}}


{{{(48*ft^2)=(4*ft^2*Q*stones)/(1*stone)}}}


{{{(48*ft^2)((1*stone)/(4*ft^2))=Q*stones}}}


{{{highlight(48(1/4)=Q)}}}


{{{highlight(highlight(Q=12))}}}
