A sector is attached to the side of a parallelogram, as shown in the diagram at right. Find the area and perimeter of the figure.

Hint:

Find the arc length of the sector to help find the perimeter.

Partial Answer:

$\text{Arc length}=2\left(12\right)\pi\left(\frac{1}{6}\right)=\frac{24\pi}{6}$

$\text{Perimeter}=4\pi+27+12+15\approx66.6$

A right slanted, Parallelogram, bottom side labeled, 15 inches, attached on its right side is a sector, whose bottom side, labeled 12 inches, is an extension, of the bottom side of the parallelogram, with angle labeled 60 degrees.
