Answer:

\displaystyle \frac{199}{18}

Step-by-step explanation:

<u>Fraction Operations</u>

Before attempting to operate with the given fractions, we need to express all of them in the form a/b, because the last 2 fractions are in mixed form.

\displaystyle 8\frac{3}{7}=8+\frac{3}{7}=\frac{8*7+3}{7}=\frac{59}{7}

\displaystyle 5\frac{11}{14}=5+\frac{11}{14}=\frac{5*14+11}{14}=\frac{81}{14}

Now for the sum of the last two fractions:

\displaystyle \frac{59}{7}+\frac{81}{14}

Make both denominators equal by multiplying by 2 both parts of the first fraction:

\displaystyle \frac{59}{7}+\frac{81}{14}=\frac{118}{14}+\frac{81}{14}

\displaystyle =\frac{118+81}{14}=\frac{199}{14}

Now multiply by 7/9:

\displaystyle \frac{199}{14}*\frac{7}{9}=\frac{199}{18}

\frac{7}{9} \times (8 \frac{3}{7} + 5 \frac{11}{14}) =  \\

\frac{7}{9} \times (8 \frac{6}{14} + 5 \frac{11}{14}   ) =  \\

\frac{7}{9} \times (13 \frac{6 + 11}{14}) =  \\

\frac{7}{9}  \times (13 \frac{17}{14}) =  \\

\frac{7}{9} \times (14 \frac{3}{14}) =  \\

\frac{7}{9} \times ( \frac{14 \times 3 + 3}{14}) =  \\

\frac{7}{9} \times ( \frac{42 + 3}{14}) =  \\

\frac{7}{9} \times ( \frac{45}{14}) =  \frac{7 \times 45}{9 \times 14} =  \frac{5}{2}  \\

Okay here is another math problem I'll give a brainliest for the right answer!
Sliva [168]
To find the total area of this figure, you have to find the area of each of the separate figures and then add those 2 answers together. Your work should look like this:

2 x 2 = 4

8 x 8 = 64

64 + 4 = 68

Your answer should be 68 ft.^2
