Answer:
119.43cm^2
Step-by-step explanation:
The computation of the area of the shaded region is shown below:
As we know that
= Area of the rectangle - Area of the circle
where,
Area of rectangle is
= 132 cm^2
And, the area of the circle is
Now the area of the shaded region is
= 119.43cm^2
We simply deduct the area of the circle from the area of the rectangle so that the area of the shaded region.
636cm.
This can be found with the Pythagorean Theorem which will give you a side length of 4.5
meters, which rounds to roughly 636cm.
