Answer: 420.25in^2
Step-by-step explanation:
Area of Square = s^2
20.5^2 = 420.25
A triangular prism is composed of 2 triangles and 3 rectangles.
1 triangle has 2 right triangle, for a total of 4 right triangles.
Area of a right triangle = ab/2 = (3.5m * 2m)/2 = 7/2 = 3.5m²
3.5m² x 4 right triangles = 14 m² total area of the triangle bases.
Rectangle: length = 11 m ; width = 4m
Area of a rectangle = L * W = 11m * 4m = 44m²
44m² x 3 rectangles = 132 m² total area of the rectangle faces
<span>Surface area = 132 m² + 14 m² = 146 m²

The answer would be disagree because it you reflected it over the x axis then it would be in the third quadrant
Hope this helps
