Answer:
56.16 m²
Explanation:
→ Work out the area of the middle rectangle
7.2 × 7.6 = 54.72 m²
→ Work out the area of the triangle on the left side
0.5 × 7 × 7.2 = 25.2 m²
→ Work out the area of the triangle on the right side
0.5 × 8.6 × 7.2 = 30.96 m²
→ As it asks for the shaded area, add up the triangle area
30.96 + 25.2 = 56.16 m²
