In ΔABC, DE is drawn parallel to BC cutting the other two sides at D and E. If AB = 3.6 cm, AC = 2.4 cm and AD = 2.1 cm, then AE is equal to:

1. 1.05 cm

2. 1.2 cm

3. 1.4 cm

4. 1.8 cm

In the given figure, ∠BAP = ∠DCP = 70°, PC = 6 cm and CA = 4 cm, then PD : DB is equal to:

1. 5 : 3

2. 3 : 5

3. 3 : 2

4. 2 : 3

In the adjoining figure, ∠ADE = ∠ABC, AE = 8 cm, EB = 7 cm, BC = 9 cm, AD = 10 cm and DC = 2 cm. Then the length of DE is:

1. 6 cm

2. 6.75 cm

3. 7.8 cm

4. 13.5 cm

In ΔABC, it is given that AB = 9 cm, BC = 6 cm and CA = 7.5 cm. Also ΔDEF is given such that EF = 8 cm and ΔDEF ∼ ΔABC. Then the perimeter of ΔDEF is:

1. 22.5 cm

2. 25 cm

3. 27 cm

4. 30 cm
