Answer 1

To find the cost of the leather piece for the book cover, multiply the area (198 square inches) by the cost per square inch ($0.25), resulting in a total cost of $49.50.

Step-by-step explanation:

The question asks us to calculate the cost of a piece of leather that will be used to make a book cover, with the dimensions given as 18 inches by 11 inches and a cost of $0.25 per square inch.

Steps to Calculate the Cost of the Leather Piece

1. Calculate the area of the rectangular piece of leather by multiplying its length by its width: Area = Length × Width.
2. Find the total cost by multiplying the area by the cost per square inch: Cost = Area × Cost per Square Inch.

Using the provided dimensions: Area = 18 in × 11 in = 198 square inches.

Then calculate the total cost: Cost = 198 sq in × $0.25/sq in = $49.50.

The cost to make the leather book cover would be $49.50.
