In Figure 5, a triangle PQR is drawn to circumscribe a circle of radius 6 cm such that the segments QT and TR into which QR is divided by the point of contact T, are of lengths 12 cm and 9 cm respectively. If the area of `Delta PQR = 189 cm^2`, then find the lengths of sides PQ and PR.

A

`4.43 m^(2)`

B

`4.432 m^(2)`

C

`4.4324 m^(2)`

D

`4.432428 m^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
As `"area" = "length" xx "breadth"`, as per rules numerical value of area has four significant digits. Therefore, (b) is the correct choice.
