Best ResponseYou've already chosen the best response.0Ok, so surface area is literally just the total area of all of the surfaces. You can use the formula \[\large (base *2)+(perimeter*height)\] The base is the base area, the perimeter is the perimeter of the base, and the height is the size of the side adjacent to the base.

Best ResponseYou've already chosen the best response.0Note: The base that you use in surface area formulas is going to be the side that appears on two sides. In this case, the base is the triangle.

Best ResponseYou've already chosen the best response.0So the surface area is 58.49?

Best ResponseYou've already chosen the best response.0Can you tell me how you got that?

Best ResponseYou've already chosen the best response.0Well what did you get for the base?

Best ResponseYou've already chosen the best response.0Well the formula for the area of a triangle is \[\large A=\frac{1}{2}*height*base\] For this triangle is the height is 3 and the base is 9.dw:1433942233346:dw

Best ResponseYou've already chosen the best response.0Right. Now put 13.5 in as the "base" in the surface area formula. \[\huge 2*base=?\]

Best ResponseYou've already chosen the best response.0I could've gotten that by multiplying 9 and 3 though right? Or do I have to use the formula?

Best ResponseYou've already chosen the best response.0Right. So that's the first half of the formula done. Now we have to figure out the perimeter and the height. Can you find the perimeter of the triangle?

anonymous

Best ResponseYou've already chosen the best response.0And that was because we were multiply the triangle area formula by 2 which will look like \[\large 2*\frac{1}{2}*3*9\] Yes, the 2 and 1/2 are going to cancel out.

Best ResponseYou've already chosen the best response.0dw:1433942566392:dw Add the sides together so \[\large 3+9+9.49=~?\]

Best ResponseYou've already chosen the best response.0What about the 37? That doesn't get added in?

Best ResponseYou've already chosen the best response.0That is going to be the "height" in the formula.

anonymous

Best ResponseYou've already chosen the best response.0Ok, so now, we're gonna multiply the perimeter (21.49) and the height (37). So \[\large 21.49*37=~?\]

Best ResponseYou've already chosen the best response.0Ok. That right there is going to be your lateral area. So 795 is the later area. To get the surface area, add on the bases. So \[\large (27)+(795)=~?\]

anonymous

Best ResponseYou've already chosen the best response.0Ok. So now you have your answers \[\huge LA=795\\\huge SA=822\]

Best ResponseYou've already chosen the best response.0And yeah, that would be it.

Best ResponseYou've already chosen the best response.0Wow ok that made a whole lot more sense than when my teacher explained it... It's still hard and confusing but I think that could change with a bit of practice.. Thank you very very much for your time!!
