30% can also be written as .3, which is easier to use in this case.
To find how many just sat around, multiply the number of people by the percentage of how many just sat around.
1400*.3=420
Hi there!
The perimeter is when you add all the sides of a shape. In a rectangle, two sides are the same, and so are the other two. So, if the two sides are 2x-3 and x+2 the expression will be:
2(2x-3) + 2(x+2)
If we were to simplify this, it would be
4x-6+2x+4
6x-2
Hope this helps!
