Question

What is the perimeter of quadrilateral ABCD?

Answer 1

The answer is 18+√26 units

Answer 2

Answer:

18+√26 units

Step-by-step explanation:

We have to find the perimeter of quadrilateral ABCD

length of AD=2-(-3)

                   =5 (since, it was a straight line from (-3,-3) to (-3,2))

length of AB=4-(-3)

                   =7 (since, it was a straight line from (-3,2) to (4,2))

length of DC=3-(-3)

                   = 6 (since, it was a straight line from (-3,-3) to (3,-3))

now, length of CD=

$\sqrt{(4-3)^2+(2+3)^2} \\\\= \sqrt{26}$

Hence, perimeter of ABCD=5+7+6+√26

                                           = 18+√26 units
