M + 12 = 10
take away 12 from both sides.
m = -2
here you gooo
you can just copy this
this is the exact squared root chart
The square would be 100.
The semicircle you will use the formula πr^2/2.
That would mean you would take the 3.14x5^2/2.
(3.14x5x5)/2
(3.14x25)/2
78.5/2
=39.25
So the total area would be 139.25
