Answer:
9 square units
Explanation:
The area of any triangle is given by:
A = 0.5 × Base × Height
From the given graph, the base of the triangle RST is RS and Height is TU
RS = 3-(-3) units = 6 units
TU = 2-(-1) = 3 units
A = 0.5 × RS × TU = 0.5 × 6 × 3 = 9 square units
Thus, area of the triangle RST would be 9 square units.
