Question

find the perimeter of the figure below, composed of a parallelogram and two semicircles. round to the nearest tenths place. answer attempt 1 out of 2 submit answer

Explanation:

Step1: Calculate the circumference of the circle

The two semicircles together form a full circle. The formula for the circumference of a circle is \(C = \pi d\), where \(d = 12\).
\(C=\pi\times12\approx3.14\times12 = 37.68\)

Step2: Add the lengths of the two straight sides

The two straight sides of the parallelogram part have length \(13\) each.
\(13 + 13=26\)

Step3: Calculate the perimeter

The perimeter \(P\) of the figure is the sum of the circumference of the circle and the lengths of the two straight sides.
\(P=37.68+26=63.68\approx63.7\)

Answer:

\(63.7\)
