the answer is  

a.

4,624π mm2

step-by-step explanation:

any line whose slope not equal to -4 does not satisfy these requirements.

step-by-step explanation:

going from (1,2) to (3, -6), x increases by 2 and y decreases by 8.   thus, the slope of a line thru those two points has the slope m = -8/2, or   m = -4.

thus, no line that has a slope different from m = -4 could be appropriate.

diagonal is     or     16.97

step-by-step explanation:

from pythagorian theorem we know,

if a is perpendicular, b is base and c is hypotenuse,

then we get

now, for a square,

perpendicular and base are equal,

since all the sides of a square are equal.

so, we get,

this is the special version of pythagorian theorem for a square.

so, if the diagonal is d and length is 12 , then we get

by square rooting we get,
