Agree with 1 and 2.
For 3
Find area of rectangle so 9x13=117
Area of triangle is 1/2(11)(5)=27.5
Add them together
117+27.5=144.5 for the total area

Answer 16

OH ok .... i agree with @nikato

Answer 17

The first figure is a parallelogram. Area is given by \[A = b*h = 5.2*2.7 = 14.04\]

The second figure is a triangle. Area is given by \[A = \frac{1}{2}b*h = \frac{1}{2}*17*4 = 34\]

The third figure is a rectangle of dimensions 9x13 and a triangle of dimensions 11x(13-8)=11x5

\[A_{total} = A_{triangle} + A_{rectangle} = \frac{1}{2}11*5 + 9*13 = 27.5+117=144.5\]

You should learn these area formulas like the back of your hand. You'll be using them often.
