Find the area of each of the following triangles:

We know that the area of triangle = 1/2 x base x height
(a) Here, base = 4 cm and height = 3 cm
∴ Area of triangle = 1/3 x 4 x 3 = 6 cm²

(b) Here, base = 5 cm and height = 3.2 cm
∴ Area of triangle = 1/2 x 5 x 3.2 = 8 cm²

(c) Here, base = 3 cm and height = 4 cm
∴ Area of triangle = 1/2 x 3 x 4 = 6 cm²

(d) Here, base = 3 cm and height = 2 cm
∴ Area of triangle = 1/2 x 3 x 2 = 3 cm²
