A triangular lawn is modelled by the triangle \(A B C\), shown in Figure 1. The length \(A B\) is to be 30 m long.
Given that angle \(B A C = 70 ^ { \circ }\) and angle \(A B C = 60 ^ { \circ }\),
- calculate the area of the lawn to 3 significant figures.
- Why is your answer unlikely to be accurate to the nearest square metre?
