A sidewalk tile measures $4$ feet by $5$ feet. How many square inches are in its area?

4 feet by 5 feet

4×5=20

Step-by-step explanation:

the area of the sidewalk tile measures 20 feet

Step-by-step explanation:

to find the are you first have to multiply the length and width so that would be 4 times 5 equals 20

-2 is the right

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.
