Question

A circular wire of diameter 42 cm is bent in the form of a rectangle whose sides are in the ratio 6:5. The area of the rectangle is (22/7)​

Answer 1

Step-by-step explanation:

Let the sides of the rectangle be 6x cm and 5x cm.

Perimeter of the rectangle = Circumference of Circle

⇒2(6x+5x)=2×722×21

⇒22x=132

⇒x=6

∴ The sides of the rectangle are 36cm and 30cm.

∴ Area of the rectangle =36×30=1080cm2
