We are given
Jim's backyard:
Length is
[tex]L=15\frac{5}{6} =\frac{95}{6} yards[/tex]
width is
[tex]W=10\frac{2}{5} =\frac{52}{5} yards[/tex]
Since, this is rectangle
so, we can find area of rectangle
[tex]A=L*W[/tex]
[tex]A=(\frac{95}{6})*(\frac{52}{5})[/tex]
[tex]A=\frac{494}{3} yard^2[/tex]
Area of one sod:
length is
[tex]l=1\frac{1}{3} =\frac{4}{3} yards[/tex]
width is
[tex]w=1\frac{1}{3} =\frac{4}{3} yards[/tex]
Since, it is rectangle in shape
so,
[tex]Area=l*w[/tex]
[tex]A=\frac{4}{3}*\frac{4}{3}[/tex]
[tex]A=\frac{16}{9}yard^2[/tex]
Number of pieces of sod:
we can use formula
Number of pieces of sod = (area of Jim's backyard)/(area of one sod)
[tex]N=\frac{\frac{494}{3} }{\frac{16}{9} }[/tex]
now, we can simplify it
[tex]N=\frac{741}{8}[/tex] pieces need ..............Answer
