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.
