the sum of internal angles of a 4-sides figure is 360° ever then


P+Q+S+R=360

we know P and R is a right angles then is 90°, then we can replace


22+Q+S+90=360

simplify


Q+S+112=360

and the angles Q and S are the same because the kite is symmetrical then Q=S

and we can replace Q=S


S+S+112=360

simplify


2S+112=360

and solve for S


\begin{gathered} 2S=360-112 \\ 2S=248 \\ S=(248)/(2) \\ \\ S=124 \end{gathered}

then right option is D 124
