The length of the rectangle is 6 cm, the width is 3 cm, how will the perimeter of the rectangle

The length of the rectangle is 6 cm, the width is 3 cm, how will the perimeter of the rectangle change if the length is reduced by 1.

To find out how the perimeter of the rectangle will change, you need to find the perimeter by the first indicators, and subtract.

Given:
Length – 6 cm.
Width – 3 cm.

Let’s remember the formula for finding the perimeter: P = (a + b) * 2.

We get:
(6 + 3) * 2 = 18 cm.

We give the condition of the problem and subtract the given value from the length.

6 – 1 = 5 cm is the new length of the rectangle.

(5 + 3) * 2 = 16 cm.

Subtract the second from the first value and find out the difference.

18 – 16 = 2 cm.

Answer: the perimeter of the rectangle has changed by 2 cm when the length is reduced by 1 cm.
