8. BIRD CAGE Buan built a bird cage with a surface area of 540 square inches. Her sister Sirib built a bird cage
with a similar shape, and it is larger than Buan's bird
cage by a scale factor of 2.25. What is the surface area
of Sirib's bird cage? Round to the nearest tenth. 210.3
3.
000

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.
