*_Answer only four questions number 1 is compulsory_*
*MAP* (MAP READING)
i)It is a source of fish which serve as food for man
ii)serve as employment to fisherman
1:100,000 =1cm represent 1km
0km 1 2 3 4 5 6 7 8km
The new scale
Old scale / New scale
= 2 / 1
let the new scale be x
1:100,000 / x = 2 / 1
X= 1:100,000 / 2
The new scale will be 1:50,000
Area (a) =length x breath
Length =8.5cm = 8. 5km
Breadth =7.2cm =7.2km
Area = 8. 5 x 7.2
