Question

Triangle ABC has vertices at A(1,2), B(4,0) and C(1,-4) Find the area of triangle ABC.

Answer 1

The area of triangle ABC from the given vertices is gotten as; 7.5

How to find the area of a triangle?

We are given the vertices of the triangle as;

A(1, 2)

B(4, 0)

C(1,-4)

The formula for area of a triangle with 3 vertices is;

Area = ¹/₂[x₁(y₂ - y₃) + x₂(y₃ - y₁) + x₃(y₁ - y₂)]

Thus;

Area = ¹/₂[1(0 + 4) + 4(-4 - 1) + 1(1 - 0)]

Area = ¹/₂(4 - 20 + 1)

Area = -7.5
