Answer:
14 cm²
Step-by-step explanation:
Area of outer square = 5 × 5 = 25 cm²
area of left square = 1 × 1 = 1 cm²
area of right square = 2 × 2 = 4 cm²
----------------------------------------------------
height of triangle = 5 - 1 = 4 cm
base of triangle = 5 - 2 = 3 cm
area of Δ = 0.5 × 3 × 4 = 6 cm²
----------------------------------------------
area of 2 squares and triangle = 1 + 4 + 6 = 11 cm²
Area of shaded card = 25 - 11 = 14 cm²
