Question
The figures are not drawn to scale. Figure 1 shows a rectangular piece of paper PRSU that measures 18 cm by 16 cm. PQ = TS = 6 cm. The paper is folded along the dotted line QT such that point R touches point U, as shown in Figure 2.
  1. Find the area of Figure 2. PQTSU, after the folding. 
  2. In Figure 2, ∠PQU is 74°. Find ∠QTS in Figure 2.
