Help ASAP please and explain

37

Step-by-step explanation:

There are 2 ways to do this, the first is to just count the number of shaded squares (35)

The second is to find the area of the larger shaded square and subtract the smaller un-shaded rectangles

The large square is 7x7=49 squares

There are two 2x3 rectangles, which are 6 each

49-6-6=37

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

h= 12 inches
