Arectangular garden has a length of 24 m and width of 17.2 m. use the correct number of significant digits to write the perimeter of the garden.

The perimeter of the garden is 82.4 meters.

Step-by-step explanation:

A rectangular garden has a length of 24 m and width of 17.2 m.

We have to find the perimeter of the garden.

Perimeter of rectangle is given as : 2W+2L =

Perimeter = 2(17.2+24)

= = 82.4 m

Hence, the perimeter of the garden is 82.4 meters.

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.
