You will want to divide the shape up into different parts to solve this. For example, first I would take the top rectangle (24x5=120) and add the answer of that to the rectangle in the middle section (120+(11x10)=230). Then, I would add the very last rectangle at the very bottom of the total we have so far (230+(7x3)=251). Lastly, I would take the semi-circle and find its area ((3.14x2)^2)/2=19.7192). Then, add all of the totals together and get your answer of
= 250.7192km^2
*note, only put the number of decimals needed.
Thanks :)

Answer:

Step-by-step explanation:
The formula of an area of a rectangle:

<em>l</em><em> - length</em>
<em>w</em><em> - width</em>
We have

Substitute:

Use FOIL <em>(a + b)(c + d) = ac + ad + bc + bd</em>
<em></em>
<em></em>
combine like terms

I haven’t done math in a year but to solve for X I think the answer will be X=10
