Need help step by step to find the total area thanks

Step-by-step explanation:

14* 20 = 280, then add 14*12/3 = 84.

Add: 280 +84 = 364.

Next, add the area of the semicircle, 100 * pi: (Approximately 314.15)

So this is 364 + 100pi(exact form) or about 478.15

Try in exact form:

364 +100Π (the symbol is pi)

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
