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.
It’s 45, as the equation for a parallelogram is A= bxh, and 9x5 is 45
Answer:
the force that must be applied by the driver to release the clutch is 21 lb
Step-by-step explanation:
Data provided:
clutch linkage on a vehicle has an overall advantage = 24:1
Applied force by the pressure plate = 504 lb
Now,
the advantage ratio is given as:
advantage ratio =
on substituting the respective values, we get
=
or
Force applied by the driver to release the clutch =
or
Force applied by the driver to release the clutch = 21 lb
Hence,
the force that must be applied by the driver to release the clutch is 21 lb
V=h*w*l
V= 5*5*5
Volume= 125
Density= Mass*Volume
