Answer

Area =\dfrac{1}{2} (Base) (Height) =\dfrac{1}{2}(2\sqrt{5})(\sqrt{5})=5 square units

Explanation

Because the right angle is at vertex B, the sides AB and BC form the base and height of the triangle. Its area is

Area =\dfrac{1}{2} (Base) (Height) =\dfrac{1}{2}(2\sqrt{5})(\sqrt{5})=5 square units

Area =\dfrac{1}{2} (Base) (Height) =\dfrac{1}{2}(2\sqrt{5})(\sqrt{5})=5 square units
