Composite Area Problem 1

The problem:

    * Have we got all the information needed?
    * Is the diagram clear. Do we need any other diagrams?
    * What are we being asked to find?
	
	    *   Break the composite shape into regular shapes.
    * What measurements do we already have?
	
	    *  Label the different regions.
    * Find the lengths of missing sides.
    * Check that all measurements are in the same units.
	
Region 1 = 11.8m × 5.9m = 69.62 m2

Region 2 = 7.5m × 5.2m = 39 m2

Region 3 = 5.4m × 9.8m = 52.92 m2	* Find the area of each region.
* Use correct units.
* Avoid rounding	
Total Area = 69.62+39+52.92 = 161.54m2

The area of roof is 161.54 m2.  	  	

    * Find the answer to the problem.
    * Will addition or subtraction be needed?
    * State the answer as part of a sentence.
    * Use correct units
