The picture shows the front wall of Buster’s doghouse that has a door cutout. The front wall and door are similar rectangles that have the dimensions shown.

90cm height
60cm length
36cm cutout length



What is h, the height of the door in centimeters?
Responses

To find the height of the door, we subtract the length of the cutout from the total height of the front wall.

h = 90cm - 36cm = 54cm

Therefore, the height of the door is 54 centimeters.
