Answer:

W=18ft

L=24ft

Step-by-step explanation:

Step one:

given data

area= 425ft^2

let the width W be =x

and the length L be =x+6

Required

Length and width

solution

Area= lenth*width

432=x*(x+6)

432=x^2+6x

x^2+6x-432=0

The roots of the quadratic equation is

x=-24-----can not be negative

x=18----correct

The dimension is

the width W =x=18ft

The length= x+6=18+6=24ft

check area= 18*24=432ft^2

Rudik [331]

Answer:

$\pi =3.160494$

Step-by-step explanation:

step 1

Find the area of the circle with a diameter of 9 units

we know that

The area of a circle is equal to

$A=\pi r^{2}$

we have

$r=9/2=4.5\ units$ ----> the radius is half the diameter

substitute

$A=\pi (4.5)^{2}$

$A=20.25\pi\ units^2$

step 2

Find the area of a square with a side length of 8 units

we know that

The area of the square is

$A=b^2$

where

b is the length side of the square

we have

$b=8\ units$

substitute

$A=(8)^2=64\ units^2$

step 3

Equate the areas

$20.25\pi=64$

solve for $\pi$

$\pi =\frac{64}{20.25}=3.160494$
