Answer 2

Answer:

Step-by-step explanation:

PQ = 20cm  [it is a rect.]

if PR is 35 cm,

         ∴RK is 35/2 = 17.5 cm

         pythaoras theorem,

               (SR)² = (SK)² + (RK)²

                .................................

                ................................

                 ......................................... SK =√ 93.75
