Answer:
2.27 m²
Step-by-step explanation:
The shaded area is the subtraction of the area of an equilateral triangle (with sides = 2 m) to the area of a square (with sides = 2 m)
Area of equilateral triangle = √3/4*a²
where a is the length of the sides of the triangle. Replacing with a = 2
Area of the equilateral triangle = √3/4*2² = √3 m²
Area of the square = a² = 2² = 4 m²
Shaded area = 4 - √3 ≈ 2.27 m²

m∠1 = 94°
m∠2 = 43°
m∠3 = 50°
m∠4 = 50°
m∠5 = 130°
m∠6 = 130°
