Answer:
6
Explanation:
There are 3 parts to each side. All three of them are the same so we only have to find the area of one different parts
Area of One Side
Triangle
The side of a square is 1 square unit.
each leg of the triangle is 1 unit
The area of 1 triangle = 1/2 * 1 * 1 = 1/2
Area of 1 side
There are 3 equal parts (3 triangles) that make up a side.
Area of the three triangles = 3 * 1/2 = 3/2 = 1.5
Area of all 4 sides
4 * 1.5 = 6
The area of the blue colored figure is 6 units.
