$$\int_{\mathrm{0}} ^{\mathrm{10}} {f}\left({x}\right){dx}\:=\mathrm{63}=\:\mathrm{Area}\:\mathrm{under}\:\mathrm{the}\:\mathrm{curve} \\ $$$$=\mathrm{S}_{\mathrm{2}} +\mathrm{S}_{\mathrm{4}} −\mathrm{S}_{\mathrm{1}} −\mathrm{S}_{\mathrm{3}} \\ $$$$\mathrm{63}=\mathrm{S}_{\mathrm{2}} +\mathrm{S}_{\mathrm{4}} −\left(\mathrm{S}_{\mathrm{1}} +\mathrm{S}_{\mathrm{3}} \right) \\ $$$$\mathrm{S}_{\mathrm{2}} +\mathrm{S}_{\mathrm{4}} =\mathrm{63}+\mathrm{31}=\mathrm{94} \\ $$
