Question

A rectangular picture frame is 5.75 inches long and 3.5 inches wide. What is the area of the glass needed to fit inside the frame?

Answer 1

`20.125"in"^2`

Explanation:

The area of the glass is equal to the area inside the frame, or `color(red)a*color(blue)b=color(red)acolor(blue)b`, where our values are `5.75"in"` and `3.5"in"`. Putting our values in, we get `color(red)a*color(blue)b=color(red)(5.75)*color(blue)(3.5)=20.125`

As both units are in inches, the answer is in inches squared, or `"in"^2`
