Answer:
Step-by-step explanation:
Area of a rectangle is given by:
....[1]
where
l is the length
w is the width of the rectangle respectively.
As per the statement:
the length of a rectangle is four times its width.
⇒
It is also given that: area of rectangle is 1024 cm square
Substitute the given values in [1] we have;
⇒
Divide both sides by 4 we have;
or
Taking square root both sides we have;
cm
Therefore, the width of the rectangle is, 16 cm

Answer:
The the exact circumference of a circle with the given radius is 200.96.
Step-by-step explanation:
Here, the radius of the given circle = 32 cm
The, Circumference of a Circle = 2 π r
So, here C = 2 x 3.14 x 32 (taking π = 3.14)
or C = 200.96
Hence, the the exact circumference of a circle with the given radius is 200.96.
