Question

In the following questions, two statements (i) and (ii) are given. Choose the valid statement.

1. The diagonals of a rhombus are 20 cm and 12 cm. Its area will be 240 cm².
2. Circumference of a circle of radius r is πr².

Options

• Only (i)

• Only (ii)

• Both (i) and (ii)

• Neither (i) nor (ii)

Answer 1

Neither (i) nor (ii)

Explanation:

(i) Area of a rhombus = `1/2` × product of diagonals. 

Here, Area = `1/2 xx 20 xx 12` = 120 cm², not 240 cm².

(ii) Circumference of a circle = 2πr, while πr² is the area of the circle; so the statement is incorrect.
