Calculate the area of the figure bounded by the graphs of the functions y = 0, y = x, x = 3.

We build a graph, after that we get a triangle, with vertices at the points: A (0, 0); B (0, 3); C (3; 3). This triangle is right-angled => Let’s use the formula to find the area of a rectangular triangle: S = 3 × 3 × 0.5 = 4.5
Answer: 4.5
