How do I find the area of a rectangle with a length of 16 that is inscribed in a circle with a radius of 10?

that person is wrong

okay so the diameter is 20. 20 is the length of the diagonal of the rectangle. then use the pythagorean theroem to show
if x is the width

20*20=16*16+ X*X

400=256+X*X

X*X= 144

X=12


12*16= 192

Area of a rectangle = height times length.

If the circle has a radius of 10, then its diameter is twice that therefore 20.

so the dimensions of the rectangle are 16 by 20.

the area would equal 16 x 20 = 320.

enable L and B be the length and breadth resply of the rectangle Now on condition that, P = 2(L + B) = 30 and A = L * B = fifty 4 or L + B = 30 / 2 L = 15-B ........eqn I and L = fifty 4/B ...... eqn II accordingly we get fifty 4 / B = 15 - B (from eqn I and II) B^2 -15B + fifty 4 = 0 B = 6 , 9 even as B is 6 L is 9 or perhaps as B is 9 L is 6 accordingly, the longest area of the rectangle is 9 inches.

If it is in the circle then the diagonal of the rectangle is the diameter of the circle. Find the diagonal using pythagorean theorem
