Question

OABC is a rhombus whose three vertices A , B and C LIE ON THE CIECLE WITH CENTRE O.If the radius of the circle is 10 cm, find the area of the rhombus ?

Answer 1

We have, AO = BO = CO = DO = 10cm

Therefore, AC = BD = 20cm

Since, the area of a rhombus =
$d_{1} \times d_{2}$
= 20 × 20
= 400

Hence, the area is 400 sq. cm..
