Yes 3x5
Multiply the length of any side by itself ("square" it). To find the are of any rectangle, including a square you multiply the length by the width, e.g. if it is a 5cm square the area is 5x5=25cm2. If it's a rectangle with a 3cm x 5cm the area is 3x5 = 15cm2.
Rectangle area = (rectangle width) x (rectangle height)
A = lw Area of a rectangle = length times width
The area of rectangle is : 35.0
Divide the area of the windows by the area of the sheets. Note: 3x5 and 2x4 are not areas, they are numbers. And you don't say how big the sheets are, so it is difficult to be helpful.
