Find the perimeter of parallelogram AFCB.
A. 14
B. 12
C. 28
D. 24

C.28

Step-by-step explanation:

It gives you 2 sides.

One of them is 8.

The other one is 12 but the 12 is divided by 2 which is 6.

Since it is a parallelogram there is the same measurements on the opposite sides.

So finally you get 6+6+8+8= 28

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
