\boxed{\text{Area of the triangle:}  \dfrac{a \times c \times sin(\measuredangle B)}{2}}  \\  \\  A =  \dfrac{a \times c \times sin(\measuredangle B)}{2}  \\  \\  A= \dfrac{11 \times 18 \times sin71 ^o }{2}   \\  \\  \\  Note : sin 71^o \approx 0,94 \\  \\  \\  A =  \dfrac{198 \times 0,94}{2}  \\  \\  A= \dfrac{186.12}{2} \\  \\ A=93.6 \ cm^2

Here is a little tip for this: The unit above cancels the unit below. So in this problem you are asked to convert pounds to ounce. So your equation will look like this. 

ounce = 2.93 pounds ( \frac{16 ounces}{1 pounds} ) = 46.88
Your ratio should involve the conversion factor. So 16 and 1 is involved canceling A and D. Then, Notice that you started with poubls. Then the ratio must have pounds at the bottom to cancel the units leaving ounces.
