Question

Rectangle A has length 12 and width 8. Rectangle B has length 15 and width 10.

Rectangle C has length 30 and width 15,
B? If so, what is the scale factor?
a, Is Rectangle A a scaled copy a of Rectangle
b. Is Rectangle B a scaled copy of Rectangle
A? If so, what is the scale factor?
C. Explain how you know that Rectangle C is not a scaled copy a of Rectangle B.
d. Is Rectangle
A.a scaled copy of Rectangle
C? If so, what is the scale factor?

Answer 1

A. Yes, Rectangle A is a scaled copy of rectangle B.

B. Yes, Rectangle B is a scaled copy of rectangle A.

C. No, Rectangle A is not a scaled copy of rectangle C.

Explanation:

Rectangle A has dimensions 12x8 and Rectangle B has length 15x10.

We see that sides of A and B are proportional because


`(12)/(15) = (8)/(10)`

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 an enlargement scale factor = 1.25 Rectangle C has 30x15, not proportion with sides of A and B. Hence we find that C is neither a scaled copy of A nor B

Hope this helps! :))
