given data:
A rectangular plot of grass is 15.4 m long and 7.3 m wide.
to find the length of the diagonal,
The diagonal equals the square root of the width squared plus the height squared.
[tex]\begin{gathered} D=\sqrt[]{15.4^2+7.3^2} \\ =\sqrt[]{237.16+53.29} \\ =\sqrt[]{290.45} \\ =17.04 \end{gathered}[/tex]The length of the diagonal is 17.04m.
