Answer:
180.48
Step-by-step explanation:
The area of a rectangle = bh
Area of a circle = π
Rectangle = 8 x 10 = 80
Circle = 3.14(
) = 200.96
But because it's a hlaf circle, divide the number by 2
100.48
Now add the numbers together
180.48
Multiply the first equation by 4 (so that both equations will have 8x terms) and then subtract:
8x-20y = -24
8x +3y = 68
------------
0 -23y = -92
Now divide both sides by -23:
y = 4
Find x by plugging y=4 into either equation:
8x +3(4) = 68
8x = 68 - 12
8x = 56
x = 7
So the answer is ordered pair is (7,4)
