At 9pm, her watch should show 8.20pm.
So she should leave at 8.20 - 45 mins = 7.35pm

39) Draw Model
5 units -> 240 - 15
1 unit -> 225/5 =45
Mark-> 2units + 15
= 105

40)
Angle a + b = 90 - 42 = 48
48/3 = 16
angle b = 16 x 2
=32

41) Draw Model
Total bought = (3 x3) + 4 = 13 units
1 unit = 130/13
= 10
Shirt = 3 unit
= 10 x 3 = 30

42a) 4 tables 10 chairs
b)12 chairs
c) 22 chairs

43) Draw Model
3 unit -> 45
1 unit -> 45/3 = 15
2 units -> 15 x 2 = $30

44) there are 10 identical sides (2 breadths = 1 length)
1 side = 30/3
= 3
Area = 2 sides x 3 sides
= 6 x 9
= 54 cm^2
