3\(\pi\)\(\sqrt{2 - 1}\)cm
\(\frac{9}{2}\)\(\pi\)cm
3 \(\pi\)(1 + \(\frac{2}{2}\))
3(1 + \(\frac{2}{2}\))
Correct answer is C
Perimeter of lunar portion = 3\(\pi\) + \(\frac{3\pi \sqrt{2}}{2}\)
= 3 \(\pi\)(1 + \(\frac{2}{2}\))

In the figure, PS bisects angle QPR. Find the ratio SR:QR.
1:2
1:3
1:4
1:5
1:6
Correct answer is C
From Internal bisection theorem, \(\frac{QP}{PR}\) = \(\frac{QS}{SR}\)
= \(\frac{4}{1}\)
= 1:4
In the figure, If PT is parallel to RS, PQ = PT, and angle SQT = 90o, Find x
35o

56.77
56.105
28:105
28:49
56:49
Correct answer is B
Area of QRST = 4 x 7 = 28
Area of PQRS = \(\frac{1}{2}\)(4 + 11) x 7
= \(\frac{7}{2}\) x \(\frac{15}{1}\)
= 28:52.5
= 56:105
