Solution:
we have given the length of the rectangular card-
and, width-
now, the area of the card will be- length×width.
so, we have-
we also have given the length of ribbon-
and, width-
so, area of the ribbon is-
length×width
now the area of shaded gray region will be-
Hence, the required expression would the above expression.

Answer:
The surface area of the triangular prism is
Step-by-step explanation:
Step 1: Finding the two area of two triangles
Area of the triangle =
Area of the triangle =
Area of the triangle = 26.117
Area of 2 triangles =
Step 2: Finding the area of the side rectangles
Area of the rectangle =
Area of the rectangle 1 = = 23.56
Area of the rectangle 2 = = 32.3
Area of the rectangle 3 = = 37.24
Step 3: surface area of the triangular prism.
Surface area of the triangular prism = 52.234 + 23.56 + 32.3 + 37.24
Surface area of the triangular prism = 145.334
