Question

Coordinate Geometry



The vertices of quadrilateral LMNO are listed below.

L(4, 2), M(12, -6), N(4, -14), O(-4, -6)

What is the approximate perimeter of the quadrilateral?

33.93 units
45.24 units
22.62 units
127.92 units

Answer 1

do you know what perimeter is

Answer 2

yes love

Answer 3

okay so you dont know how to calculate length of side by co-ordinates given?

Answer 4

ya thts the problem

Answer 5

distance formula
d^2=(x-x)^2 + (y-y)^2
so distance btwn L(4, 2), M(12, -6)
would be \[d=\sqrt{(4-12)^2 + (2-(-6))^2} = \sqrt{8^2 + 8^2} = \sqrt{128}\]

Answer 6

can you find for other sides

Answer 7

i say tht it is B butid

Answer 8

calculate and check,dont guess
