3.

 

Area of rectangle +  area of triangle

 

Base * height   +  (1/2) Base * Height

 

9 *  13         +     (1/2) (11) *  (13 - 8)   =

 

9 * 13    +   (1/2) (11) (5)   =

 

117   +  (1/2) (55)   =

 

117 +  27.5  =

 

144.5   cm^2

 

 

4.  Area of parallelogram  = Base x Height

 

240   =  Base  x  20           divide both sides by 20
