We have 3 rectangles  whose combined area =  W x H =

7x  5  

7 x 5

7 x 6

 

And we have two triangles each with a base of 6 and a height of 4

 

Work through this and I'll help if you get stuck......

Well lets see

 

7 x 5=35

 

7 x 5=35

 

7 x 6=42

 

6 x 4=24

 

6x4=24 

 

Now we add all this up so 

 

35+35+42+24+24 = 160

 

Tell me if I have to divided any by 1/2 please!

OK...you got the rectangles correct

 

Remember that the area of a triangle   = (1/2) base * height

 

Refigure the areas of the two triangles

129 would be the answer

Figure this again

 

Area of rectangles  = 112

 

Area of triangles  =  (1/2) (24 + 24 )

Figure this again

 

Area of rectangles  = 112

 

Area of triangles  =  (1/2) (24 + 24 )

 

112+24 = 136 units
