Question

Find area of the square, whose vertices lies on the circle of radius 20 cm.​

Answer 1

Answer:

if the square lies on circle of radius 20 cm the side of square will be 20cm

area of square=side^2

=20^2

=400cm^2

Answer 2

SINCE THE SQUARE IS INCCRIBED IN A CIRCLE SO ITS DIAGONAL = CIRCLE'S RADIUS

SO, DIAGONAL = 20 cm .

NOW , SINCE , DIAGONAL = √2 SIDE OF SQUARE

So, SIDE = 20 / √2 = 10√2 cm

SO AREA OF SQUARE = SIDE² =( 10√2 )² = 200 cm²
