Answer:
Step-by-step explanation:
(1) As definition, the area (
) of a circle is calculated by:
x 
with 
is radius of circle.
(2) The relation between radius () and diameter (
) of a circle is:
= 2 x
(3) Applying the Pythagorean theorem for a square with sides of length 
,
the relation between side and diagonal 
is:
=> The diagonal () of that square is calculated by:
= 
(4) The square fits exactly inside a circle, with each of its vertices being on the circumference of the circle.
Applying the theorem of inscribed angle in a circle, the measure of arc BD is twice as the measure of inscribed angle BAD.
In other words, the measure of arc AC = 2 x 90 = 180 deg, or half of circle.
It means that the diagonal BD is coincide with a diameter of circle.
=> 
or 
x =
or = 
Substitute back into original formula used for calculating the area of circle:
=> A = 
x 
= x 
=> 
x 
=> 
x 
= 
x = 5.97 cm
Hope this helps!

I have included attachment below
so since a rhombus is 2 pairs of paralell sides, we can cut it into 4 triangles
we can see that we can take the bottom 2 triangles and put them on top to get a rectangle that is width 21 and height 32/2 (16=height
area of rectangle=legnth times width=16 times 21=336 m^2
answer is 336 m^2
