30% discount
Step-by-step explanation:
To find the percent discount write a proportion.
Cross multiply numerator with denominator of each fraction to solve for x.

70 = x
This means you pay 70% of the price. The discount was 30%.
The perimeter of a rectangle is all sides added up, so length + length + width + width.
L = length
W = width
then the perimeter is L+L+W+W, or 2L + 2W, or 2(L+W).
what's the length? well, is just 2(27).
L = length
