If the length and width of a rectangle are each increased by ten percent, then the perimeter of the rectangle is increased by what percent?
-------------
Perimeter = 2(L + W)
---
New Perimeter = 2(1.1L + 1.1W)
---
New Perimeter = 2(1.1)(L+W)
NP = 2.2(L+W) = 2(L+W) + 0.2(L+W)
-----
The increase is 0.20 = 20%
