Question 1191236

the area of patio is

{{{A[1]=4x*3.1x}}}

{{{A[1]=12.4x^2}}}


The area of the flower bed will be {{{A[2]=3.52}}}, and since we have  a square flower bed, the length of the side is

{{{x=sqrt(3.52)=1.88}}}


The area of the paving stones is the area of patio minus the area of the flower bed

{{{A=A[1]-A[2]}}}

{{{A=12.4x^2- 3.52}}}

{{{A=12.4*1.88^2- 3.52}}}

{{{A=40.31}}}->the area of the paving stones
