hi mariah
i am slightly confused with the word encircled (which imply circle), to me we must find the area restricted with lines
it looks like right triangle, so if we find the legs of triangle we can find its area
it is easy to construct lines x=2, y=3, and y=x-6, and then to find coordinates of the vertex
x=2, and y=x-6 insert x=2 to the y=x-6,y=2-6=-4, so the first leg will equal=3+4=7
y=3, and y=x-6, here insert y=3 into the y=x-6, 3=x-6, x=9 thte second leg will equal 9-2=7 also 7
and now the area=1/2*7*7=49/2
but if we need to find the area if the circle inscribed into the given triangle we must first find radius, r= (leg1+leg2-hypotenuse)/2=(7+7-2*7^1/2)/2=7-7^1/2
S=pi*(7-7^1/2)^2
