Answer:
width = 11 feet
Step-by-step explanation:
The perimeter of a rectangle is 2 times length + width.
He already decided that the perimeter is at most 60 feet and the length is 19 feet. Then replacing in the formula for perimeter you have:
60 = 2 ( 19 + width)
30 = 19 + width
11 = width

We have been given that on the day of his 18th birthday Harry decided to start saving money regularly
. Starting on that day, he could save 30.00 on the same date every month. We are asked to find the amount saved by the day before Harry's 60th birthday.
First of all, we will find years from 18 years to 60 years.

To find total amount saved, we will multiply 504 months by amount saved per month.


Therefore, Harry would have saved
by the day before his 60th birthday.
