The perimeter of the door is 5.30cm. The width is 1cm. What is the length?

P = 2L + 2W

5.30 = 2L + 2
3.30 =2 L
1.65 = L

This is a strange door. It's slightly larger than a postage stamp.

gerbils?

Ms. Sue is correct. This door is probably for a doll house

To find the length of the door, we can use the formula for the perimeter of a rectangle:

Perimeter = 2 * (length + width)

Given that the perimeter is 5.30 cm and the width is 1 cm, we can substitute these values into the formula:

5.30 cm = 2 * (length + 1 cm)

Now, let's solve for the length:

Divide both sides of the equation by 2:

5.30 cm / 2 = length + 1 cm

2.65 cm = length + 1 cm

Subtract 1 cm from both sides of the equation:

2.65 cm - 1 cm = length

1.65 cm = length

Therefore, the length of the door is 1.65 cm.
