What is eight times a number equals 4 times the 9?

x=4.5

Step-by-step explanation:

8*x = 4*9

8x = 36

x = 4.5

9/2

Step-by-step explanation:

Let the unknown number = n

Therefore, we can decode your question in the following manner:

8 x n = 4 x 9

Recognize that 4 x 9 = 36

So, 8 x n = 36

Lets divide 8 in both sides

n = 36/8 = 9/2

Therefore, n = 9/2

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
