Question:Find the area of the triangle defined byand

Short Answer

Expert verified

Therefore, the Area of triangle is 25.

Step by step solution

01

Definition. 

Basically, it is equal to half of the Area of the parallelogram.

The area of a triangle is defined as the total region that is enclosed by the three sides of any particular triangle.

A = 1/2 脳 b 脳 h.

02

Given. 

Given Matrix,

and .

03

To find the area of the triangle.

Since the area of a triangle formed by two vectors is equal to half the area of a parallelogram formed by the same vectors, we compute

Therefore,

Area of triangle is 25.
