Use a net to find the surface area of the right triangular prism shown below: three rectangles next to each other with a width of 7 feet. the first and second rectangles length are unknown, and the last is 10 feet long. there are two right triangles above and below the last rectangle. one is labeled with a base of 6 feet and a height of 8 feet.

3 is greater then both of those numbers

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.
