pishuonlain [190]

Answer:

60ft

Step-by-step explanation:

Let's x, y be the width and length of the surrounding rectangle. Since the area is 450 sq feet, this means xy = 450 or y = 450/x

The perimeter of this rectangle is (since there are 3 sides only)

f(x,y) = 2x + y

This is something we need to minimize. We can start by substituting y = 450/x

f(x) = 2x + 450/x

Let's take the first derivative of this function and set it to 0

$f'(x) = 2 - \frac{450}{x^2} = 0$

$2 = \frac{450}{x^2}$

$x^2 = 450 / 2 = 225$

$x = \sqrt{225} = 15ft$

y = 450 / 15 = 30ft

so the minimum perimeter that needs taping over is

f(x,y) = 2x + y = 2*15 + 30 = 60ft

8090 [49]

Answer:

36 inches

Step-by-step explanation:

lets think of it as a ratio,

80:w

20:9

so we want 20 to get to 80

and 9 to get to w right?

so if we just move the smaller rectangle to the corner, then 20*4=80 right?

and if we do that, we do it to 9 as well, 9*4=36

w=36
