The drawing shows a concrete walkway around a pool. What is the total area of the concrete? Question 17 options:

A)

65 ft2

B)

150 ft2

C)

165 ft2

D)

50 ft2m

answer: it is d

step-by-step explanation:

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

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.
