<h2>
Maximum area is 25 m²</h2>
Explanation:
Let L be the length and W be the width.
Aidan has 20 ft of fence with which to build a rectangular dog run.
Fencing = 2L + 2W = 20 ft
L + W = 10
W = 10 - L
We need to find what is the largest area that can be enclosed.
Area = Length x Width
A = LW
A = L x (10-L) = 10 L - L²
For maximum area differential is zero
So we have
dA = 0
10 - 2 L = 0
L = 5 m
W = 10 - 5 = 5 m
Area = 5 x 5 = 25 m²
Maximum area is 25 m²
Suppose you have 192
marbles.
You want to group this marble into 15 groups.
What we need to do is simply divide the given numbers
=> 192 is our dividend and 15 is our divisor
=> 192 / 15
=> 12.8 , thus there are 12 groups with a remainder of 8.
Now, convert this into fraction
=> 12 is our quotient, 8 is our remainder to use as our numerator and
192 as our denominator.
thus the fraction value of this is :
=> 12 8/192
Using that 1 mile = 1,6 km so 5 miles = 5*1,6 = 8 km
and 250 miles = 250*1,6 = 400 km
