I have to find the surface area of this figure. Round to the nearest hundredth.

OpenStudy (tacotime):

area of triangles * 5 + area of base (its a pentagon) = surface area

OpenStudy (shaleiah):

1485?

OpenStudy (triciaal):

looks like you could find the perpendicular height using pythagorean theorem. the base looks like a pentagon of side 16 so when you "open" you have a rectangle the area would be the perimeter of the base multiplied by the height you calculated

OpenStudy (triciaal):

do you have answer choices?

OpenStudy (shaleiah):

No answer choices, I just have to find the surface area of this figure.
