Answer:
Option B
Step-by-step explanation:
Surface area of a triangular prism = Area of the triangular sides + Area of the rectangular sides
Area of the triangular sides = 2(Area of the triangular base)
                                               = ![2[\frac{1}{2}(\text{Base})(\text{Height})]](https://tex.z-dn.net/?f=2%5B%5Cfrac%7B1%7D%7B2%7D%28%5Ctext%7BBase%7D%29%28%5Ctext%7BHeight%7D%29%5D)
                                               = 10 × 12
                                               = 120 ft²
Area of the rectangular sides = (Perimeter of the triangular side)(Height of the prism)     
= (10 + 13 + 13)(15)
= 36 × 15
= 540 ft²
Surface area of the prism = 120 + 540
                                            = 660 square feet
Option B will be the answer.

Origin = (0,0) 
To find the units of distance subtract the given pair from origin
(0,4) - (0,0) = 4
