Find the scale factor of Figure B to Figure A.

Step-by-step explanation:

Shape A is similar to shape B, but shape B is tilted in a different direction. If you tilt B so that it is in the same direction as A, they will look more similar. The ratios of A's sides are 20:24:12:28

The ratios of B's sides are 15:18:9:21

To get from B to A, you have to multiply all the sides by , making   the scale factor.

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
