Answer:
Rectangle B is a scaled copy of rectangle A.
Enlargement scale factor = 1.25
Step-by-step explanation:
Rectangle A:
Length = 12 units
Width = 8 units
Rectangle B:
Length = 15 units
Width = 10 units
Rectangle C:
Length = 30 units
Width = 15 units
Rectangle B length ÷ rectangle A length = rectangle B width ÷ rectangle A width = 1.25
i.e [tex]\frac{15}{12}[/tex] = [tex]\frac{10}{8}[/tex] = 1.25
Hence rectangle B is a scaled copy of rectangle A and the scale factor of enlargement is 1.25
Answer:
a) Yes. Rectangle A is a scaled copy of rectangle B.
b) Yes. Rectangle B is a scaled copy of rectangle A.
d) No. Rectangle A is not a scaled copy of rectangle C.
Step-by-step explanation:
Rectangle A has dimensions 12x8 and
rectangle B has length 15x10
We see that sides of A and B are proportional because
[tex]\frac{12}{15} =\frac{8}{10}[/tex]
So we say that since sides are proportional A and B are similar or scaled copy of each other.
Since A is smaller and B is bigger,
A is 0.8 scaled copy of B.
Similarly B has
Enlargement scale factor = 1.25
Rectangle C has 30x15
i.e. not proportion with sides of A and B.
Hence we find that C is neither a scaled copy of A nor B.
