Question 834211: a rectangle with one side 4 c.m. is
inscribed in a circle of
radius 2.5 c.m. then find
the aria of rectangle?

Since the radius is 2.5, the diameter is 5.
A diagonal for the rectangle is equal to this diameter.
We have a triangle with side lengths of 5 and 4.
5 is the hypotenuse. Set x = the length of the
other side of the triangle.
So
add -16 to each side
x = 3
We have side lengths of 3 and 4 so
the area = 3*4 = 12
