Recall that the equation to find the perimeter of a rectangle is 2(L + w)
Since we know the length, we can make an equation:
2(3 + w) = 12
Divide both sides by 2:
(3 + w) = 6
w = 3
Now that we know both length and width, we simply have to find their product to solve for area:
a = L * w
a = 3 * 3
a = 9
The area of the rectangle is 9 cm^2.
Answer:
512
Step-by-step explanation:
There are 1760 yards in a mile.
It would take the bee (400/(20*1760)*60*60)=40.909 seconds
If my calculations are correct
1)5gallons--->10 fish
20 gallons---->(20*10/5)=40
10fish--->5gallons
1fish---->(1*5/10)=0.5 gallons
10--->5
50--->(50*5/10)=25 gallons
I believe the answer is -9<span />
