4) split this into two shapes, a rectangle and a triangle... Rectangle: base(height) 14(7)=98 Triangle: 1/2base(height) Find the height: 14-7=7 1/2(14)(7)=49 Add them together: 98+49=147 147in^2
5) split this into two shapes, a square and a triangle... Square: base(height) 20(20)=400 Triangle: 1/2base(height) 1/2(20)(10)=100 Add them together: 400+100=500 500m^2
6) split this into 2 shapes, a rectangle and a triangle... Rectangle: base(height) 6(5)=30 Triangle: 1/2base(height) 1/2(6)(3)=9 Add them together: 30+9=39 39yd^2
7) I can't see the number behind the m. Please tell me what it is and then I'll help you!
8) split this into 2 shapes, a rectangle and a triangle... Rectangle: base(height) 5(2)=10 Triangle: 1/2base(height) 1/2(5)(3)=7.5 Add them together: 10+7.5=17.5 17.5ft^2
9) split this into 2 shapes, a rectangle and a triangle... Rectangle: base(height) 13.5(18)=243 Triangle: 1/2base(height) 1/2(13.5)(9)=60.75 Add them together: 243+60.75=303.75 303.75cm^2
