Please help calculate the surface area

200

Step-by-step explanation:

SA = LA + 2B     where LA is the lateral area and B is the area of the base(triangle)

LA = ph     p = perimeter of base and h = distance between bases

LA = (5 + 5 + 6)11 = 176

B = bh/2 = 6(4)/2 = 12

SA = 176 + 2(12) = 176 + 24 = 200

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.
