GENERAL OBJECTIVES:
On completion of this section, students should
1. understand that the attributes of an object can be quantified using measurements;
2. appreciate that all measurements are approximate and that the relative accuracy of a measurement is dependent on the measuring imstrument and the measurement process;
3. demonstrate the ability to use concepts in measurement to model and solve realworld problems.

SPECIFIC OBJECTIVES:
The student should be able to:

CONTENT 
1. 
Calculate the perimeter of a polygon, a circle, and a combination of polygons and circles; 

2. 
Calculate the length of an arc of a circle; 

3. 
Calculate the area of polygons, a circle and any combination of these; 
rectangle, square, parallelogram, trapezium, rhombus and circle.

4. 
Calculate the area of a sector of a circle 
Estimate the area of irregularly shaped figures

5. 
calculate the area of a triangle given two sides and the included angle; 
Optional Specific Objective:
Area of Δ = ^{1}/_{2} abSinC.

6. 
calculate the area of a segment of a circle. 
Optional Specific Objective.

7. 
estimate the area of irregularly shaped plane figures; 

8. 
calculate the surface area of solids; 
Prism, cylinder, cone, sphere, cube and cuboid.

9. 
calculate the volume of solids; 
Prism, cylinder, pyramid, cone, sphere, cube and cuboid.

10. 
convert units of length, area, capacity, time and speed; 

11. 
use the appropriate SI unit of measure for area, volume, mass, temperature and time (24 hour clock) and other derived quantities; 

12. 
solve problems involving time, distance and speed; 

13. 
estimate the margin of error for a given measurement; 
Sources of error. Maximum and minimum measurements.

14. 
use maps and scale drawings to determine distances and areas. 

15. 
Sovle problems involving measurement. 

Here are our measurement tutorials to help you prepare for this section of the CXC math exam. 
the maths is very helpful. I
the maths is very helpful. I think tha you should do some examples on vectors
