Find the surface area of the triangular prism below.​

Surface area of the triangular prism = 186.984 feet²

Step-by-step explanation:

Surface area of the triangular prism is given by the expression,

Surface area = (Perimeter of the triangular base)×Height + Area of the triangular bases

Perimeter of the triangular base = (9.8 + 8.5 + 6.2)

                                                      = 24.5 ft

Height of the prism = 5.5 ft

Area of the triangular base =

                                             =

                                             = 26.117 square feet

Surface area of the prism = (24.5 × 5.5) + (26.117 × 2)

                                           = 134.75 + 52.234

                                           = 186.984 square feet

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
