The width of a rectangle is 3 feet, and the diagonal is 5 feet. what is the area of the rectangle?

Area= Length * Width

3*5= 15

The area of the rectangle is 15.

I hope this helps! 

To find the width of a rectangle or square is very simple. The formula is as follows;

area = length * width

Now, considering that the shape you have listed is a rectangle, all we must do is take the 5 and 3 and multiply.

5 * 3 = 15

There you have it, your answer is 15.
