Level 3
The figures are not drawn to scale. Figure 1 shows a rectangular piece of paper ACDF that measures 20 cm by 14 cm. AB = ED = 5 cm. The paper is folded along the dotted line BE such that point C touches point F, as shown in Figure 2.
Find the area of Figure 2. ABEDF, after the folding.
In Figure 2, ∠ABF is 76°. Find ∠BED in Figure 2.
