Question

Select the correct answer from each drop-down menu.
A publisher displays its latest magazine cover on its website.
The publisher scales up the front cover of the magazine using a scale of 6 centimeters to 1 inch. The length of the scale drawing is 48 centimeters, and its width is 66 centimeters.
The length of the actual magazine cover is
inches.
The width of the actual magazine cover is
inches.
The scale drawing is too big to view on a computer screen without scrolling. So, the publisher uses a new scale of 4 centimeters to 1 inch.
The length of the new scale drawing is
centimeters.
The width of the new scale drawing is
centimeters.

Answer 1

Given:

The length of the initial scale drawing = 48 cm

The width of the initial scale drawing = 66 cm

Initial scale = 6 cm to 1 inch

Final scale = 4 cm to 1 inch

To find:

1. The length of the actual magazine cover is  inches.
2. The width of the actual magazine cover is  inches.
3. The length of the new scale drawing is  centimeters.
4. The width of the new scale drawing is  centimeters.

Solution:

If the scale is 6 cm to 1 inch

Then 48 cm will be 48/6 inch = 8 inch

And 66 cm will be 66/6 = 11 inch.

Therefore the length of actual magazine = 8 inches and width = 11 inches.

Since the new scale is 4 cm to 1 inch

Then 48 cm of scale drawing will become 48*4 / 6 = 32 cm

And 66 cm will become 66*4/ 6 = 44 cm

Therefore the length of new scale reading is 32 cm and width is 44 cm.
