Calculate the area of triangle QRT, given QR = 830 m, QT = 370 m, and angle QTR = 51.2 degrees.

Here's a step-by-step solution to the problem.

First, we will use the values explicitly shown in the diagram, as there are inconsistencies between the text description and the diagram.
From the diagram:
$QR = 830 \, \text{m}$
$QT = 370 \, \text{m}$
$TS = 720 \, \text{m}$
$RS = 750 \, \text{m}$
$\angle QTR = 51.2^\circ$
$\angle TSR = 43.5^\circ$

a) Calculate the area of triangle QRT correct to 1 dp.

Step 1: Find $\angle QRT$ using the Sine Rule in $\triangle
