Question

What is the area of triangle RST

Answer 1

Area: (2×3)/2+(3×4)/2=9units²

Answer 2

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.
