The height of the window is 18 dm, which is 60 cm more than the width. What are the area and perimeter of the window?

Let’s express the height of the window in centimeters.

18 dm = 180 cm.

Let’s find the width of the window, which is less than its height by 60 cm.

To do this, subtract 60 cm from the height of 180 cm.

180 – 60 = 120 cm.

Let’s find the area of the window.

To do this, multiply the width value by the window height value.

180 x 120 = 21,600 cm².

Find the perimeter of the window.

To do this, add twice the width to twice the height of the window.

180 x 2 + 120 x 2 = 360 + 240 = 600 cm.

Answer: The area of the window is 21,600 cm².

The perimeter of the window is 600 cm.
