Use the image to answer the question.
An illustration of a triangular pyramid net shows an inverted equilateral triangle as the base, with sides measuring 17 millimeters. Three identical isosceles triangles extend from each side of the base. A dashed line bisects the central inverted triangle and is labeled as h equals 14.72 millimeters. The outer edges of the three isosceles triangles joined to the 17 millimeter base are all labeled as 11 millimeters. A dashed line bisects the outer triangle on the left and is labeled as h equals 10.99 millimeters.
Write the equation for the surface area of the triangular pyramid net shown in the image. Remember, SA=(12base⋅height)+(12perimeter⋅slant height)
