The Total Surface Area for the shape below is _. (round to nearest tenth.)

=193.2 cm

Step-by-step explanation:

Figure out the triangles first Area= Base times Height divided by 2first figure out one triangle A= (6)(5.2)/2 = 15.6 (brackets means times and the slash means dividetimes it by 2 so you get the area of both triangles (15.6)(2)= 31.2Now figure out the rectangles Area= Base times HeightA=(6)(9) = 54 Then times it by 3 to get the area of all three triangles(54)(3)= 162Now add 162 and 31.2 and you get 193.2 cm

Ican't read this very blury

so the perpendicular line goes through the given pointyou would get a perpendicular line at some random location

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
