1 5 2 + 2 0 2 = 2 5 2 ⟹ Right angled triangle 15^2 + 20^2 = 25^2 \implies \text{Right angled triangle} ∴ Area = Product of legs 2 ⟹ 15 ⋅ 20 2 = 150 \therefore \text{Area} = \frac{\text{Product of legs}}{2} \implies \frac{15 \cdot 20}{2} = \boxed{150}

It is a 3-4-5 right triangle.

Area = (1/2)(15*20) = 150 square units
