Answer:
50.4 cm²
Step-by-step explanation:
The figure is composed of a square and a triangle
area of square = 5.6² = 31.36 cm²
area of Δ = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 5.6 ( side of square ) and h = 12.4 - 5.6 = 6.8 , then
area of Δ = 0.5 × 5.6 × 6.8 = 19.04 cm²
Then
A of ABCED = 31.36 + 19.04 = 50.4 cm²
