There are 23 square green blocks in the figure, and the note up in the corner
shows us that each square has (1 inch x 1 inch) = 1 square inch of area.
You ought to be able to handle it from here.
8X - 6X = -18
2X = -18
X = -9.
Hope this helps!
<em>Answer:</em>
<h3>The answer is 201 in²</h3>
<em>Explanation:</em>
Use the formula <u>Area = pi * r²</u>
<em>(Radius is half the diameter.)</em>
First lets solve for x we know 3x=90. In this case x=30. Now we can solve for y. We know the triangle needs to equal 180 so y+2(30)=180. So we get y=120. Hope it helps
