The length of a rectangle is 7 feet. if the perimeter is 42 feet, what is the width of the rectangle

The perimeter of a rectangle is found by multiplying the length by 2 and then adding that to the width multiplied by 2.

The length is 7, multiplied by 2 = 7x2 = 14.

Subtract that from the total perimeter:

42 - 14 = 28

The length of the 2 widths is equal to 28, to find the length of 1 width, divide that by 2:

Width = 28 / 2 = 14

The width is 14 feet.

Both of them are correct depends on what they variable are they trying to get.
Jared is trying to get the value of y in terms of x using the second equation. On the other hand, Nicole is trying to get the value of x in terms of y using the second equation. both of them will end up getting the same thing.
