<span>The question is asking us to determine the length of the floor of a rectangular deck. The rectangular deck has an area of 600 squared feet. The floor is 20 feet wide ( W = 20 ft ). Formula for the area of the rectangle is: A = L x W. 600 = L X 20; L = 600 : 20; L = 30 ft. Answer: The floor is 30 ft long.</span>

Answer:
33.3%
Step-by-step explanation:
The number of people that must be fed has increased from 4 to 6, so is 6/4 = 3/2 as many as planned.
Assuming the additional people eat the food at the same rate as the original people, the time and number of people are assumed to be inversely proportional. That is, the time the food will last is 2/3 of the originally expected time. It has decreased by 1/3 × 100% = 33.3%.
___
If you like, you can count rations. For four people for 12 days, at 3 rations per person per day, a total of 144 rations are needed. When the number of people becomes 6, the number of days that will last is ,,,
(144 rations)/(6 persons)/(3 rations/person/day) = 8 days
The percentage change in trip days is ...
(8 -12)/12 × 100% = -4/12 × 100% = -33.3% . . . a decrease of 33.3%
