Answer:
(1)
And we know that the lenght is y = 20.3. If we solve for x from equation (1) we got:


And replacing we got:

And the width for this case would be 15.8 in
Step-by-step explanation:
For this case we know that the photo is rectangular. Let's define:
x = the width, y= the length
And we know that the perimeter is given by:
(1)
And we know that the lenght is y = 20.3. If we solve for x from equation (1) we got:


And replacing we got:

And the width for this case would be 15.8 in
The footage of the room with a rental price of $1500 is 709 square foot

Linear equation</h3>
A linear equation is given by:
where m is the rate of change, b is the initial value of y, y, x are variables.
Let y represent the monthly rental price and x represent the square footage. Given the equation:
y = 0.7752x + 950.25
For a rent of $1500:
1500 = 0.7752x + 950.25
The footage of the room with a rental price of $1500 is 709 square foot
