What is the perimeter of the rectangle shown on the coordinate plane, to the nearest tenth of a unit? 13.4 units 17.9 units 26.8 units 40.0 units

see the attached figure to better understand the problem

Let

x------> the length side of a rectangle

y-------> the width side of a rectangle

we know that

the perimeter of a rectangle is equal to the formula

in this problem

Step 1

Find the distance AB

we know that

the distance's formula between two points is equal to

substitute the values

Step 2

Find the distance BC

tex]B(2,8)\\C(4,4)[/tex]

we know that

the distance's formula between two points is equal to

substitute the values

Step 3

Find the perimeter

we know that

the perimeter of a rectangle is equal to the formula

we have

substitute the values of the distance in the formula

therefore

the answer is

The perimeter of the rectangle is equal to
