The sides of the triangle (i.e., a, b, c) are of 122 m, 22 m, and 120 m respectively.
Perimeter of triangle = (122 + 22 + 120) m
2s = 264 m
s = 132 m
By Heron's formula
Area of a triangle =\( \sqrt{\text{s(s - a)(s - b)(s - c)}}\)
= \(\sqrt{\text{132(132 - 122) (132 - 22) (132 - 120)}}\)
\(= \sqrt{\text{132 × 10 × 110 × 12}}\)
= 1320 m2
Rent of 1 m2 area per year = ₹ 5000
Rent of 1 m2 area per month = \(₹ \frac{5000}{12}\)
Rent of 1320 m2 area for 3 months = \(₹ \)(\(\frac{5000}{12}\)) × 3 × 1320
= \(₹\)1650000
Therefore, the company paid ₹ 16,50,000 as rent.
Let \( A = \begin{bmatrix} \frac{1}{\sqrt{2}} & -2 \\ 0 & 1 \end{bmatrix} \) and \( P = \begin{bmatrix} \cos \theta & -\sin \theta \\ \sin \theta & \cos \theta \end{bmatrix}, \theta > 0. \) If \( B = P A P^T \), \( C = P^T B P \), and the sum of the diagonal elements of \( C \) is \( \frac{m}{n} \), where gcd(m, n) = 1, then \( m + n \) is:
