Question

I need help please! The cover of Martina’s book measures 7 1/4 inches by 9 inches. What is the area of the book cover?

Answer 1

65 1/4 square inches.

Explanation:

Common knowledge:

A book has a shape of either a square (tiny book) or a rectangle (normal size). But, the 2 side lengths are different, which means this is a rectangle.

So, we have to use the formula for a rectangle:

`A=lw` with l being the length and w being the width

We know that the length is 9 inches and the w is 7 1/4, so we can substitute:

A=9(7.25)

solve

A=65.25

So the area of this book is 65.25 or 65 1/4 square inches.

Hope this helps! :)
