Will give any wanted points!! help quick!!

Here , the ratio UV:VW and UT:TS will be in proportion , so ;

${:\implies \quad \sf \dfrac{UV}{VW}=\dfrac{UT}{TS}}$

Putting the given values ;

${:\implies \quad \sf \dfrac{18}{36}=\dfrac{UT}{24}}$

${:\implies \quad \sf UT=\dfrac{1}{2}\times 24}$

${:\implies \quad \bf \therefore \quad \underline{\underline{UT=12 \:\: units}}}$
