What is the perimeter of the quadrilateral ABCD?

Given:

The figure of a quadrilateral ABCD.

To find:

The perimeter of the quadrilateral ABCD.

Solution:

In an isosceles triangle, the two sides and base angles are congruent.

In triangle ABD,

              [Given]

is an isosceles triangle      [Base angle property]

                  [By definition of isosceles triangles]    

                  ...(i)

In triangle BCD,

       [Given]

All interior angles of the triangle BCD are congruent, so the triangle BCD is an equilateral triangle and all sides of the triangle area equal.

     [Using (i)]               ...(ii)

Now, the perimeter of quadrilateral ABCD is:

Therefore, the perimeter of the quadrilateral ABCD is 35 units.

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.

hope i
