S(ABCDEF)=28.75=((115)/4)  {consider a rectangle around it and   calculate S}  a=coefficient of similar=((AE)/(AE))=(1/2)  S(ABCDEF)=a^2 S(ABCDEF)=((115)/(16))
$${S}\left({ABCDEF}\right)=\mathrm{28}.\mathrm{75}=\frac{\mathrm{115}}{\mathrm{4}} \\ $$$$\left\{{consider}\:{a}\:{rectangle}\:{around}\:{it}\:{and}\:\right. \\ $$$$\left.{calculate}\:{S}\right\} \\ $$$${a}={coefficient}\:{of}\:{similar}=\frac{{AE}}{{AE}}=\frac{\mathrm{1}}{\mathrm{2}} \\ $$$${S}\left({ABCDEF}\right)={a}^{\mathrm{2}} {S}\left({ABCDEF}\right)=\frac{\mathrm{115}}{\mathrm{16}} \\ $$
