IM 7.1.9 Practice: Creating Scale Drawings

An image of a book shown on a website is 1.5 inches wide and 3 inches tall on a computer monitor. The actual book is 9 inches wide. What scale is being used for the image?

An image of a book shown on a website is 1.5 inches wide and 3 inches tall on a computer monitor. The actual book is 9 inches wide. How tall is the actual book?

The flag of Colombia is a rectangle that is 6 ft long with three horizontal strips.
  • The top stripe is 2 ft tall and is yellow.
  • The middle stripe is 1 ft tall and is blue.
  • The bottom stripe is also 1 ft tall and is red.

Create a scale drawing of the Colombian flag with a scale of 1 cm to 2 ft.

Create another scale drawing of the Colombian flag with a scale of 2 cm to 1 ft.
