1 inch to 4 feet: 8 inch^2 to 128 feet^2

1 inch to 5 feet: 5 inch^2 to 125 feet^2

1 inch to 3 feet: 13 inch^2 to 117 feet^2

1 inch to 2 feet: 12 inch^2 to 48 feet^2

Step-by-step explanation:

When converting square units, you have to square the original conversion rate. For examples, if 1 inch equals 4 feet, 1^2=1 square inch equals 4^2=16 square feet. Do this for each conversion above.

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.
