first triangle=bxh/2
                  =3x4/2
                 =6in squared
rectangle=l x w
              =3 x 10
               =30in squared

trapezoid=3+5x2/2
                 =8in squared
                6 + 30 + 8
                   =44 in squared

The triangle is 1/2 bh or 6.
The rectangle is lw or 30.
The trapezoid is ((a+b)/2)h or 8 
The total is 44 in^2
