A rectangle is 6 tiles wide by 12 tiles high. How many
tiles are in the rectangle?
Show your work.

Well it’s 2d and how many tiles in the rectangle is an area question

In this case we just multiply since w*l is area but in this case width is 6 and length (height) is 12

so 6*12= 72

72 tiles

Step-by-step explanation:

Here you have to multiply. Why?

Think of a graph. To find the area we need to use the formula length times width. (a = l x w)  So we use 6 tiles wide and 12 tiles high as out length and width.

6 = width

12 = length

Now multiply

6 x 12 = 72

Hope this helps! Please comment if it does or not and if it needs adjustment. :)

step-by-step explanation:

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
