Answer: Area = 4w² + 30w + 36
Step-by-step explanation:
Let w represent the width of the rectangular patio.
The rectangle patio has a length four times its width. It means that the length of the patio is 4w.
The formula for determining the area of a rectangle is expressed as
Area = length × width
If the boarder is 3 ft, the combined length of the patio and the boarder would be (4w + 3 + 3) = (4w + 6) feet
Also, the combined width of the patio and the boarder would be
(w + 3 + 3) = (w + 6) feet
Therefore, the expression for the area of the patio and boarder is
Area = (4w + 6)(w + 6)
Area = 4w² + 24w + 6w + 36
Area = 4w² + 30w + 36
Answer: Option 'A' is correct.
Explanation:
Cost of 9 ounces of apples = $1.89
Cost of 1 ounce of apple is given by
Now, if he bought 1 pound of apple,
Cost of 1 pound of apple = $2.49
Cost of 16 ounces = $2.49
(∵ 1 pound = 16 ounces)
Cost of 1 ounce of apple is given by
So, Second option is the least expensive if he bought 1 pound of apple for $2.49
Then, he will save which is given by
Hence, option 'A' is correct.
