If the diagonal of a square is 11.3 meters, approximately what is the perimeter of the square

The perimeter of the square is

Step-by-step explanation:

we know that

The perimeter of a square is equal to

where

b is the length side of the square

Step 1

Find the length side of the square

The diagonal of the square is equal to

Applying the Pythagoras Theorem

In this problem we have

------> solve for b

substitute the value of d

Step 2

Find the perimeter of the square

Substitute the value of b

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.
