Perimeter the coordinates of the vertices of a quadrilateral are r(-1,3), s(3,3), t(5,-1), and u(-2,-1)

The perimeter is equal to  or

Step-by-step explanation:

we have

The coordinates of the vertices are

R(-1,3), S(3,3), T(5,-1), and U(-2,-1)

plot the figure to better understand the problem

see the attached figure

we know that

The perimeter of a quadrilateral is the sum of its four length sides

so

the formula to calculate the distance between two points is equal to

step 1

Find the distance RS

substitute the values

step 2

Find the distance ST  

substitute the values

step 3

Find the distance TU

substitute the values

step 4

Find the distance UR  

substitute the values

step 5

Find the perimeter

substitute the values

-----> exact value

-----> approximate value

the answer is 3/5

step-by-step explanation:

first divide 24 divided by 8 because that is the least common multiple

then divide 40 by 8

then you will get 3/5.
