Find the perimeter of a rectangular area with a length of 13 inches and
a width of 7 inches using distributive property and not using it.
P=2(L+W)
P=2(13+7)
P= 40
What does L+W mean
length of 13 inches and
a width of 7 inches
Now what do suppose L and W are?
AKIRRA showed you one way.
Also -
P = 2L + 2W
P = 2(13) + 2(7)
P = 26 + 14
P = ?
