Answer:
237.46 cm squared
Step-by-step explanation:
look at the image for explanation
First of its y-y1 = m(x-x1)
m is the slope, what it is increasing by.
y1 is the y intercept of your pair.
X1 is the x intercept of your coordinate pair, plug them in. If you dont know slope the formula to find it is:
y2-y1/x2-x1
I believe it would be (b) (-2,1)
For the square area we have:
12.12=144
and for the rectangle we have:
4.11=44
