The vertices of a quadrilateral are shown. P(3,7), Q(7,15), R(17,10), S(13,2)
What is the area of the quadrilateral?
A. 100 square units
B. 80 square units
C. 50 square units
D. 125 square units

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60

d. all of the above

step-by-step explanation:

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
