Correct Answer: True
Manaus, the capital of Amazonas state, lies where the Negro River meets the Amazon River. This site is famous for the “Meeting of Waters,” where the two rivers flow side by side without mixing immediately.
Manaus serves as an important inland port and commercial hub in the Amazon Basin. It facilitates trade, transportation, and access to remote areas of the rainforest.
\[ \textbf{Manaus is an important inland port at the confluence of the Negro and Amazon rivers.} \]

In the following figure \(\triangle\) ABC, B-D-C and BD = 7, BC = 20, then find \(\frac{A(\triangle ABD)}{A(\triangle ABC)}\). 
The radius of a circle with centre 'P' is 10 cm. If chord AB of the circle subtends a right angle at P, find area of minor sector by using the following activity. (\(\pi = 3.14\)) 
Activity :
r = 10 cm, \(\theta\) = 90\(^\circ\), \(\pi\) = 3.14.
A(P-AXB) = \(\frac{\theta}{360} \times \boxed{\phantom{\pi r^2}}\) = \(\frac{\boxed{\phantom{90}}}{360} \times 3.14 \times 10^2\) = \(\frac{1}{4} \times \boxed{\phantom{314}}\) <br>
A(P-AXB) = \(\boxed{\phantom{78.5}}\) sq. cm.
