I have chosen to do the questions 4,7, and 8 in the homework book on page 33.
The ladder reaches 5.9m up the wall.
The quadrilateral is not a rectangle because 289cm +676cm does not equal 961cm, it equals 965.
8. 20 km/h for 10h west equals 200km
20 km/h for 7 1/2h south equals 150km
40,000km + 22,500km= 62500km
The ship is 250km away from the port.
