We can multiply each side by 14ft yo find the value on feet and late calculate the area
[tex]\begin{gathered} 8\times14=112ft \\ 10\times14=140ft \\ 6\times14=84ft \end{gathered}[/tex]
tha area formula is
[tex]A=\frac{b\times h}{2}[/tex]
where b=84ft and h=112ft
[tex]\begin{gathered} A=\frac{84\times112}{2} \\ A=4704 \end{gathered}[/tex]
the area is 4,704ft2
