The perimeter of the rectangle is the sum of its dimensions
The dimensions that minimize the perimeter are 
The area is given as:
Let the dimension be x and y.
So, we have:
Make x the subject
The perimeter is calculated as:
Substitute
Expand
Differentiate
Set to 0
Rewrite as:
Divide both sides by -1
Multiply y^2
Divide by 2
Take square roots of both sides
Substitute in
Hence, the dimensions that minimize the perimeter are

Surface area of a cuboid
= [2(length)(width)] + [2(width)(height)] + [2(height)(length)]
= {[2(4)(2.5)] + [2(2.5)(2)] + [2(2)(4)]} units²
= (20 + 10 + 16) units²
= 46 units²
After 75% increase followed by a 33 1/2% decrease the net increased is 16.375%.
<u>Solution:</u>
Need to determine net percentage increase or decrease when a value is increased by 75% and then decreased by 
that is 33.5%.
Let’s assume initial value be represented by variable x.
Now there is decrease of 33.5%
Hence after 75% increase followed by a decrease the net increased is 16.375%.
D) . -100 is the answer, but if you do it the calculator wayy it's likee thiss,
the way i waa taught wass this beloww ↓
20 1
__ / ( -_ )
1 5
that will givee youu, -0.2 witch leadss too -100
-hope this helps .
It would be 3840. The pattern is: x2, x4, x6, x8, x10. Hope that helps! :) :D
