Answer:
length = 100 m
width = 63.66 m
Step-by-step explanation:
Let's call
x: lenght of rectangle
y: width of rectangle, and also diameter of the semicircles
Perimeter: 2*x + π*y = 400
or:
x = 200 - π/2*y
Area of the rectangle = x*y
Replacing:
A = (200 - π/2*y)*y
A = 200*y - π/2*y²
At the maximum:
dA/dy = 200 - π*y = 0
y = 200/π
y = 63.66 m
and
x = 200 - π/2*63.66
x = 100 m
How do you simplify i^68 = One
8 Is total of a whole piece of a whole. So 3 were token from the whole.
