Answer 3: Area of pentagon ABCDE = Area of ∆ AEN + Area of trapezium EDMN + Area of ∆ DMC + Area of ∆ ACB = 1 2 × AN × EN + 1 2 × EN + DM × NM + 1 2 × MC × DM + 1 2 × AC × BL = 1 2 × AN × EN + 1 2 × EN + DM × AM - AN + 1 2 × AC - AM × DM + 1 2 × AC × BL = 1 2 × 6 × 9 + 1 2 × 9 + 12 × 14 - 6 + 1 2 × 18 - 14 × 12 + 1 2 × 18 × 4 cm 2 = 27 + 84 + 24 + 36 cm 2 = 171 cm 2 Hence , the area of the given pentagon is 171 cm 2 . Answer 4: Area of hexagon ABCDEF = Area of ∆ AFP + Area of trapezium FENP + Area of ∆ ALB = 1 2 × AP × FP + 1 2 × FP + EN × PN + 1 2 × ND × EN + 1 2 × MD × CM + 1 2 × CM + BL × LM + 1 2 × AL × BL = 1 2 × AP × FP + 1 2 × FP + EN × PL + LN + 1 2 × NM + MD × CM + 1 2 × MD × CM + 1 2 × CM + BL × LN + NM + 1 2 × AP + PL × BL = 1 2 × 6 × 8 + 1 2 × 8 + 12 × 2 + 8 + 1 2 × 2 + 3 × 12 + 1 2 × 3 × 6 + 1 2 × 6 + 8 × 8 + 2 + 1 2 × 6 + 2 × 8 cm 2 = 24 + 100 + 30 + 9 + 70 + 32 cm 2 = 265 cm 2 Hence , the area of the hexagon is 265 cm 2 . Answer 7: We will find the length of AC . From the right triangles ABC and HGF , we have : AC 2 = HF 2 = 5 2 - 4 2 cm = 25 - 16 c m = 9 c m AC = HF = 9 c m = 3 c m Area of the given figure ABCDEFGH = Area of rectangle ADEH + Area of ∆ ABC + Area of ∆ HGF = Area of rectangle ADEH + 2 Area of ∆ ABC = AD × DE + 2 Area of ∆ ABC = AC + CD × DE + 2 1 2 × BC × AC = 3 + 4 × 8 + 2 1 2 × 4 × 3 cm 2 = 56 + 12 cm = 68 cm 2 Hence , the area of the given figure is 68 cm 2. Answer 8: Let AL = DM = x cm LM = BC = 13 cm ∴ x + 13 + x = 23 ⇒ 2 x + 13 = 23 ⇒ 2...
