Answer:

502.3

Explanation:

Step1: Calculate parallelogram area

$A_{1}=32\times13 = 416$

Step2: Calculate semi - circle area

Radius $r = \frac{13}{2}$, $A_{2}=\frac{1}{2}\pi r^{2}=\frac{1}{2}\pi\times(\frac{13}{2})^{2}=\frac{169\pi}{8}\approx 66.3$

Step3: Calculate total area

$A = A_{1}+A_{2}=416 + 66.3=482.3$ (There was a calculation error above, correct as follows)

Step1: Calculate parallelogram area

The base of the parallelogram is $32$ and the height is $13$. The area formula of a parallelogram is $A_{p}=b\times h$. So $A_{p}=32\times13 = 416$.

Step2: Calculate semi - circle area

The diameter of the semi - circle is $13$, so the radius $r=\frac{13}{2}$. The area formula of a semi - circle is $A_{s}=\frac{1}{2}\pi r^{2}$. Substitute $r = \frac{13}{2}$ into the formula: $A_{s}=\frac{1}{2}\pi\times(\frac{13}{2})^{2}=\frac{169\pi}{8}\approx\frac{169\times3.14}{8}=\frac{530.66}{8}=66.3325$.

Step3: Calculate the total area of the figure

$A = A_{p}+A_{s}=416+66.3325 = 482.3325\approx482.3$ (Wrong, re - calculate)

Step1: Calculate parallelogram area

The base of the parallelogram $b = 32$ and height $h = 13$. Using the formula $A_{1}=b\times h$, we get $A_{1}=32\times13=416$.

Step2: Calculate semi - circle area

The diameter of the semi - circle is $13$, so radius $r=\frac{13}{2}$. The area of a semi - circle formula is $A_{2}=\frac{1}{2}\pi r^{2}=\frac{1}{2}\times\pi\times(\frac{13}{2})^{2}=\frac{169\pi}{8}\approx\frac{169\times3.14}{8}= 66.3325$.

Step3: Total area

$A=A_{1}+A_{2}=416 + 66.3325=482.3325\approx482.3$ (Incorrect, correct calculation)

The diameter of the semi - circle $d = 13$, so the radius $r=\frac{13}{2}$. The area of the semi - circle $A_{semicircle}=\frac{1}{2}\pi r^{2}=\frac{1}{2}\times\pi\times(\frac{13}{2})^{2}=\frac{169\pi}{8}\approx\frac{169\times3.14}{8}=66.3325$.
