part a and b only i was actually looking for c

Step-by-step explanation:

for part b

Area of DEF= 1/2× base × height = 1/2× 2 × 1 = 1

Area of FGD= 1/2× base × height = 1/2× 2.24 × 1.34 =1.50  

Area of GBD= 1/2× base × height = 1/2× 2 × 1 = 1

Area of ABG= 1/2× base × height = 1/2× 4.12 × 0.49 =1.01

Area of BCD= 1/2× base × height = 1/2× 1.41 × 2.12 =1.49

The approximate area of the original polygon is 6 square units
