Answer: There are 20 ways and 1680 ways respectively.
Step-by-step explanation:
Since we have given that
Total number of blocks = 6
Number of red blocks = 3
Number of green blocks = 3
So, Number of patterns she can make by placing them all in a line is given by
![\dfrac{6!}{3!\times 3!}\\\\=20](https://tex.z-dn.net/?f=%5Cdfrac%7B6%21%7D%7B3%21%5Ctimes%203%21%7D%5C%5C%5C%5C%3D20)
If there are 3 white blocks
so, total number of white blocks becomes 9
So, Number of total pattern she can make by placing all nine blocks in a line is given by
![\dfrac{9!}{3!\times 3!\times 3!}\\\\=1680\ ways](https://tex.z-dn.net/?f=%5Cdfrac%7B9%21%7D%7B3%21%5Ctimes%203%21%5Ctimes%203%21%7D%5C%5C%5C%5C%3D1680%5C%20ways)
Hence, there are 20 ways and 1680 ways respectively.

Answer:
Length = 10
Width = 13
Step-by-step explanation:
If the width of a rectangle is 3 units less than the length and if the area is 130 square units, the length is 10 units and the width is 13 units.
Formula: A=wl
Therefore, you have to find what two numbers multiply together in order to recieve 130 units.
A=wl=13·10=130
