13. 5 minutes
Step-by-step explanation:
This is a simple proportion problem. Make two fractions where one item is always on the top and the other on the bottom.
Now, cross multiply (multiply the two numbers diagonal from each other and divide the diagonal with the x value)
576 x 3 = 1, 728
1, 728 / 128 = 13.5
The equation to find area is:
A is your area, l is your length, and w is your width. Let's insert the numbers we already have, which are our area and our width.
To solve this, we must divide both 11l and 264 by 11, to get our variable l all alone on one side.
264 / 11 = ?
Solve this, and you'll have your length :)
