Ben sawed a board into four pieces
with lengths of 0.63m, 0.20m, 0.58m,
1.09m. What was the total length of the
board?

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.

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .

the answer is 8.64
