Chloe has enough sand to fill a sandbox with an area of 36 square units. She wants the outer edges of the sandbox to use as litt
sergiy2304 [10]

Answer:

The dimensions of the box is 6 × 6 units.

Step-by-step explanation:

Chloe fill a sand box whose area is 36 square units.

Let length be x units and width be y units.

Area of box = 36

xy=36\\y=\dfrac{36}{x}\ \ \ ...(i)

Perimeter of box, P=2(x+y)

P=2(x+\dfrac{36}{x})\ \ \ \ \ \ \ \ [\text{ From }(i)]

Differentiate w.r to x

\dfrac{dP}{dx}=2(1-\dfrac{36}{x^2})

For critical point, \dfrac{dP}{dx}=0

\therefore 2(1-\dfrac{36}{x^2})=0

\Rightarrow x=\pm6

x can't be negative.

\dfrac{d^2P}{dx^2}=\dfrac{144}{x^3}\\\dfrac{d^2P}{dx^2}|_{x=6}=\dfrac{144}{216}>0(\text{min})

P_{min}=24 units

Hence, Length = 6 units and width = 6 units

MA_775_DIABLO [31]
It is irrational.

A = π r^2 = π[3/4 cm]^2 = 9π/16 cm^2

An irrational number (Pi in this case) multiplied by a rational number (9/4) gives an irrational number.
