What is the perimeter of the quadrilateral formed by joining the points P(-5, 1), Q(3, 7), R(6, 3), and S(-2, -3)?

A. 30 Units
B.
C. 42 Units
D.

The answer to your question is the letter A. 30 units

Step-by-step explanation:

Data

P (-5, 1)

Q (3, 7)

R (6, 3)

S (-2, -3)

Process

1.- Find the distance from P-Q, Q-R, R-S, and P-S

dPQ =

dPQ =

dPQ =

dPQ =

dPQ = 10 units

dQR =

dQR =

dQR =

dQR =

dQR = 5 units

dRS =

dRS =

dRS =

dRS =

dRS = 10 units

dPS =

dPS =

dPS =

dPS =

dPS = 5 units

2.- Calculate the Perimeter

Perimeter = 10 + 5 + 10 + 5

               = 30 units

a = 11 : 4

b = 38

c = 1 for every 6

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
