**Answers :**

1/ no. of sides x width x height / 2 = 4 (750 x 1000 / 2) = 1 500 000 square m

2/ 880 / 25 = 35.2 hours = 35 hours and 12 mins

3/ 830 / 8.3 = 100 trips

4/ 89 – 19 = 70 degrees

5/ hours per week x stamping rate = (24 x 7 = 168) x 12 = 2016

6/ 67 + 27 + 52 + 79 = 225 km

7/ 300 / 2.5 = 120 hours

8/ (800 x 900 = 720 000) x 3 / 2 x 8 = 8 640 000 coconuts
