By finding the area of the rectangle, we will see that she will need 150 ft^2 of flooring.
<h3>
How to get the area of the rectangle?</h3>
For a rectangle of length L and width W, the area is:
A = L*W
And the perimeter is:
P = 2*(L + W).
In this case, we know that the length is 5ft longer than the width, so we can write:
L = W + 5ft
We also know that the perimeter is 50ft, so we can write:
P = 50ft = 2*(W + 5ft + W)
50ft = 4*W + 10ft
40ft/4 = W = 10ft
So the width is 10 ft, and then the length will be:
L = 10ft + 5ft = 15ft
So the area of the rectangle is:
A = 10ft*15ft = 150 ft^2
She will need 150 ft^2 of flooring.

Answer:
The first one is correct.
Step-by-step explanation:
Given :
In 2006, 65.2 million people subscribed to cable television.

It is wrong because 14/24 should convert to 1/2 not 7/12
The weeks will it take the grass to grow 12 over 7 centimeters is 3 weeks.
<h3>What is the unitary method?</h3>
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
St. Augustine grass can grow at the rate of 4 over 7 centimeters per week.
The weeks will it take the grass to grow 12 over 7 centimeters
4/7 x = 12/ 7
28x = 84
x = 84/28
x = 3
The weeks will it take the grass to grow 12 over 7 centimeters is 3 weeks.
