Area of one big square = 1 square meter
Now the bigger square is divided into 9 smaller square
Area of 9 small squares = Area of 1 big square= 1 square meter
So applying unitary method we can find are of 1 small square.
Area of 1 small square = 1/9 square meter
Now each small square is divided into two identical triangles.
So ,
Area of 1 triangle = 1/2 of area of 1 small square =(1/2) (1/9) = 1/18 square meter
Again applying unitary method to find area of 6 triangles,
Area of 6 triangles = 6 * area of 1 triangle = 6 * (1/18) = 1/3 square meter
Answer : Area of 6 triangles is 1/3 square meters.
