Answer:
true
Step-by-step explanation:
ed and fg are parallel
Statements in option A and D are true
Step-by-step explanation:
Step 1 :
Length of the given rectangle = 10 cm
Width of the given rectangle = 4 cm
Step 2 :
A)
Apply scale factor of 3
New width is 4 * 3 = 12 cm
Hence the statement in option A is true
Step 3 :
B)
Scale factor = 4
New length is 10 * 4 = 40 cm
Hence option B is false
Step 4 :
C)
Scale factor = 2
New length is 10 * 2 = 20 cm
New width is 4 * 2 = 8 cm
New perimeter is 20+20+8+8 = 56 cm
Hence option C is false
Step 5 :
D)
Scale factor = 2
New length is 10 * 2 = 20 cm
New width is 4 * 2 = 8 cm
New area is 20*8 = 160 sq cm
Hence option D is true
I think it would be A.
Maybe not because they are all negatives.
7 = Hundreds
2 = Tens
9 = Ones
