Using the rule of thirds to evaluate the composition of a well-crafted painting, that eye should be attracted to <span>one or more points of interest.</span>
First you will divide;
200÷4=50
Then you multiply;
50×9=450
Last you add;
2000+450=2450
Your conclusion would equal
x = 5
A single stepping stone as you have said is 20 inches sqaure. This means that it has an area of 20.
All you would need to do then is multiply 20 by 30 to get the area of thirty tiles. The result of this would be 600.
If you mean one side of the stepping stone is 20 inches then you would multiply 20 by 20 to get the area of one, since that would be multiplying length times width (the area formula). The area of one would result in 400 and you would then multiply this by the thirty tiles (400 times 30) to get 12000.
