Answer:
Area = length x width (in feet)
Explanation:
The area of a 2-dimensional shape can be found by multiplying its length by its width. The equation to find the area of a rectangle is:
Area = length x width
So if you know the length and width of a piece of glass in feet, you can use the above equation to find its area in square feet. For example, if the length of the glass is 10 feet and the width is 5 feet, the area would be:
Area = 10 feet x 5 feet = 50 square feet
So the equation to find the area of a piece of glass in square feet is:
Area = length x width (in feet)
It's worth noting that this equation applies to any 2-dimensional shape that has a length and a width, not just a rectangle.
