3. Lisa is decorating the outside edge of a square picture frame. She needs to know the side length of the frame. The area of the frame is m square inches. What is the side length of the frame in inches? Show your work below.​

Step-by-step explanation:

All of it because it’s a square all of its sides are equal

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.
