Answer:
Scale factor = 36
Step-by-step explanation:
R is a biggest rectangle and C is the smallest rectangle in the picture
attached.
Rectangle R = 4 × [Rectangle B]
= 4 × [9 × rectangle C] {since rectangle B is formed by joining 9 rectangles of C}
= 36 × rectangle C
This shows that R is a scaled copy of C.
Since, scale factor = [tex]\frac{\text{Measure of R}}{\text{Measure of C}}[/tex] [Scale factor for rectangle R from C]
= [tex]\frac{36C}{C}[/tex]
= 36
Therefore, scale factor by which C is enlarged to form R is 36.
