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:
Option (2)
Step-by-step explanation:
Volume of a prism A (preimage) = 27 cubic units
Factor of dilation of the sides of this prism (image) =
Volume scale factor of these prisms =
Since, Volume scale factor = (Scale factor of dilation of the sides)³
=
=
Now from the formula of volume scale factor,
Volume of the image prism = = 3 cubic units
Therefore, Option (2) will be the answer.
