Answer:
Step-by-step explanation:
ΔBCE:
h = 4cm; b= ?
5² = 4² + b²
b = 3cm
Area of Triangle = 1/2 × bh
= (1/2) × 3 × 4
= 6cm²
Area of Rectangle ABED = l×b
= 4 × 3
= 12 cm²
Area of ACED = 12 + 6 = 18 cm²

Answer:
A of BCE = 6 Cm^2
A of ACED =18 Cm^2
Step-by-step explanation:
we can see that : EB = DA = 4cm
in triangle BCE:
(EC)^2 = (EB)^2 +(BC)^2
BC = ROOT( 25 - 16) = root(9)
BC= 3cm
Area of triangle = 1/2 × base × height
= 1/2 ×3 × 4
= 6 cm^2
Area of rectangle ABED:
= length × breadth
= 4 × 3
= 12 cm^2
Area of ACED = 12 + 6
= 18 Cm^2
