Answer:
26 cm²
Step-by-step explanation:
The area of the triangle measuring 7cm by 4cm (including the unshaded part) is:
Area(A) = Length(L) × Width(W)
A = 7cm × 4cm = 28 cm²
Area of the unshaded part = 2 cm × 1 cm = 2 cm²
Area of the shaded shape = Area of the 7 cm by 4 cm rectangle minus the area of the unshaded region = 28 cm² - 2 cm² = 26 cm²
