# Find the area of

Given: – Vertices of the triangle:

(– 1, – 8), (– 2, – 3) and (3, 2)

We know that,

If vertices of a triangle are (x1,y1), (x2,y2) and (x3,y3), then the area of the triangle is given by:

Now, substituting given value in above formula

Expanding along R1

sq.units

as area cannot be negative

Therefore, 15 sq.unit is the area

Thus area of triangle is 15 sq.units
