Answer:

$b=6.8\ units$

Step-by-step explanation:

we know that

Applying the law of sines in the triangle ABC

$\frac{AB}{sin(C)}=\frac{AC}{sin(B)}$

substitute the given values

$\frac{15}{sin(140\°)}=\frac{b}{sin(17\°)}$

Solve for b

$b=(sin(17\°))\frac{15}{sin(140\°)}$

$b=6.8\ units$

Hi,
Let assume a the width and b the length of the rectangular area.
$\left \{ {{2a+b=116} \atop {a*b=1682}} \right. \\\\

 \left \{ {{b=116-2a} \atop {a*(116-2a)=1682}} \right. \\\\

 \left \{ {{b=116-2a} \atop {a^2-58a+841=0}} \right. \\\\

 \left \{ {{b=116-2a} \atop {(a-29)^2=0}} \right. \\\\

 \left \{ {{a=29} \atop {b=116-2*29}} \right. \\\\

 \left \{ {{a=29} \atop {b=58}} \right. \\\\
