The rectangle has a perimeter of 18 ft with a length of 6 ft. a new rectangle is formed by decreasing the width of the original rectangle by 1 foot and keeping the same length. how will the perimeter of the new rectangle compare with the perimeter of the original rectangle?

18x6 is 108

17x6 is102

Step-by-step explanation:

The new perimeter will be 2 feet shorter.

Step-by-step explanation:

You are subtracting 1 foot from the width, meaning you are subtracting 1 foot from each of 2 sides. If you do that, your new perimeter would be 16 feet.

Original width:

6×2=12

18-12=6

6÷2=3

The original width was 3 feet.

To find the new perimeter:

3-1=2

2×2=4

6×2=12

4+12=16

The new perimeter is 16 feet, 2 feet shorter than the original (18 feet).
