Question
The figures are not drawn to scale. Figure 1 shows a rectangular piece of paper HKLN that measures 22 cm by 16 cm. HJ = ML = 6 cm. The paper is folded along the dotted line JM such that point K touches point N, as shown in Figure 2.
  1. Find the area of Figure 2. HJMLN, after the folding. 
  2. In Figure 2, ∠HJN is 75°. Find ∠JML in Figure 2.
