Answer:The area of the acquired trapizum is 12m².
Step-by-step explanation:
• ABCD is a square with side 4m.
E is the midpoint of BC.
• In ∆CDE,
CD=4m
CE=2m (E is midpoint of BC)
angle DCE=90°
• area of ∆CDE=1/2 ×CE×DC
=1/2 × 2 × 4 =4m²
• area of square ABCD=(4)²
=16m²
• area of trapizum ABED=area of square ABCD - area of ∆CDE
= (16-4)m²
= 12m²
