BC= 39

Explanation:

4z+4z+3z+3+3z+3=174

8z+6z+6=174

14z+6=174

Subtract 6 from both sides

14z=168

Z=12

So then 3*12+3=39

And you can check by doing 39+39+48+48
And it equals 174

Answer:

28.25 square units

Step-by-step explanation:

A circumference of the circle is

$C=2\pi r,$

where r is the radius of the circle.

So,

$18.84=2\pi r\\ \\r=\dfrac{18.84}{2\pi}=\dfrac{9.42}{\pi}\ cm$

The area of the circle is

$A=\pi r^2$

Substitute the value of the radius:

$A=\pi \cdot \left(\dfrac{9.42}{\pi}\right)^2=\dfrac{9.42^2}{\pi}\approx 28.25\ un^2$
