An Isosceles Right Triangle is a right triangle that consists of two equal length legs.
i.e opp = adj
hyp\(^2\) = adj\(^2\) + opp\(^2\)
2\(^2\) = x\(^2\) + x\(^2\)
4 = 2x\(^2\)
2 = x\(^2\)
√2 = x

Correct answer is D
Area of sector = \(\frac{\theta}{360°} \times \pi r^2\)
= \(\frac{60}{360} \times \frac{22}{7} \times 3.5 \times 3.5\)
= \(\frac{77}{12}\)
= \(6\frac{5}{12}\) cm\(^2\)
