Answer:

<u>log 7</u>

Step-by-step explanation:

Adding the first values :

<u><em>Applied Rule : log a + log b = log(ab)</em></u>

⇒ log (14/3) + log (11/5)

⇒ log (14/3 × 11/5)

⇒ <u>log (154/15)</u>

Subtracting the second values :

<u><em>Applied Rule : log a - log b = log(a/b)</em></u>

⇒ log (154/15 ÷ 22/15)

⇒ log (154 ÷ 22)

⇒ <u>log 7</u>

Answer:

log7

Step-by-step explanation:

when adding logs, apply the log rule: \log _a\left(x\right)+\log _a\left(y\right)=\log _a\left(xy\right)

∴  \log\left(\frac{14}{3}\right)+\log\left(\frac{11}{5}\right)=\log\left(\frac{14}{3}\cdot \frac{11}{5}\right)

when subtracting logs, apply the log rule: \log _a\left(x\right)\:-\:\log _a\left(y\right)=\log _a\left(\frac{x}{y}\right)

\log\left(\frac{14}{3}\cdot \frac{11}{5}\right)-\log\left(\frac{22}{15}\right)=\log\left(\frac{\frac{14}{3}\cdot \frac{11}{5}}{\frac{22}{15}}\right)\\\\=\log\left(7\right)

area \: of \: trapezoid  \\ =  \frac{1}{2}  \times (4 + 2) \times 2 \\  \\  = 6 \:  {units}^{2}

Area of shape = area of square + area of triangle

= 2^2 + \frac{1}{2} \times 2\times 2\\= 4 + 2\\= 6\: units^2 \\
