Question

the area A of a rectangle parking lot is given by the equation A=16s^2+25. jacob knows the area of the parking lot and wants to find s. Solve A=16s^2+25 for s

Answer 1

s = sqrt(A - 25)/4

Explanation:

A = 16s^2 + 25

Switch sides.

16s^2 + 25 = A

Subtract 25 from both sides.

16s^2 = A - 25

Divide both sides by 16

s^2 = (A - 25)/16

Take the square root of each side.

s = sqrt[(A - 25)/16]

s = sqrt(A - 25)/4

Answer 2

The required form in terms of A the value of s is
`s=\sqrt{(A-25)/(16)}`

Explanation:

Given : The area A of a rectangle parking lot is given by the equation
`A=16s^2+25`. Jacob knows the area of the parking lot.

To find : Solve
`A=16s^2+25` for s?

Solution :

The area A of a rectangle parking lot is given by the equation

`A=16s^2+25`

To solve the given expression for s, we have to separate the s and take it to one side.

Subtract 25 from both side,

`A-25=16s^2+25-25`

`A-25=16s^2`

Divide both side by 16,

`(A-25)/(16)=(16s^2)/(16)`

`(A-25)/(16)=s^2`

Taking root both side,

`\sqrt{(A-25)/(16)}=√(s^2)`

`\sqrt{(A-25)/(16)}=s`

So, The required form in terms of A the value of s is
`s=\sqrt{(A-25)/(16)}`
