Verified Answer :

we know that side AC=5 and BD=3. The area of a triangle is baseheight/2, so the area of this triangle is 35=2=7.5

Answer:

The area of the triangle is 7.5 sq units.

Step-by-step explanation:

The coordinates of the vertices of triangle ABC is,

A = (2, 1)

B = (-1, 4)

C = (2, 6)

D = (2, 4)

So,

\(AC=\sqrt{(2-2)^2+(6-1)^2}=\sqrt{0^2+5^2}=\sqrt{5^2}=5\)

\(BD=\sqrt{(-1-2)^2+(4-4)^2}=\sqrt{(-3)^2+0^2}=\sqrt{9}=3\)

we know that,

\(\text{Area}=\dfrac{1}{2}\times \text{Base}\times \text{Height}\)

\(=\dfrac{1}{2}\times \text{AC}\times \text{BD}\)

\(=\dfrac{1}{2}\times 5\times 3\)

\(=7.5\)
