Answer:
Rectangle B is a scaled copy of rectangle A.
Enlargement scale factor = 1.25
Step-by-step explanation:
<u>Rectangle A:</u>
Length = 12 units
Width = 8 units
<u>Rectangle B:</u>
Length = 15 units
Width = 10 units
<u>Rectangle C:</u>
Length = 30 units
Width = 15 units
Rectangle B length ÷ rectangle A length = rectangle B width ÷ rectangle A width = 1.25
i.e =
= 1.25
Hence rectangle B is a scaled copy of rectangle A and the scale factor of enlargement is 1.25
