Question

Base of a coloured flag which is in the shape of triangle is 2 + √2 units and height is 2 – √2 units. Then the area of flag in square units. 

A) 2 

B) 1/2

C) 1 

D) 4

Answer 1

Correct option is (C) 1

Area of flag \(=\frac12\times\) Base \(\times\) Height

\(=\frac12\times(2+\sqrt2)\times(2-\sqrt2)\)

\(=\frac{4-2}2\) = 1 square units

Answer 2

Correct option is  C) 1
