Mass, acceleration of gravity, and height
Measure the width and the length and multiply the two measurements together.
Find the measurements from one corner along the wall to the next corner and then repeat with the wall next to it. Once you've found the measurements, multiply them together to find the square footage.
You need three things: m = mass of the object (in kilograms) g = gravitational acceleration constant (usually 9.8 m/s^2) h = height of the object, usually from the ground (in meters) The gravitational potential energy are these three values multiplied together: PE = m • g • h
Using a metric tapemeasure,multiply the length of your rectangle by the width.

Mass, acceleration of gravity, and height
You multiply an object's mass by the acceleration due to gravity (9.81 m/s^2) and the height above a reference point to find its gravitational potential energy. The formula for gravitational potential energy is PE = mgh, where m is the mass in kg, g is the acceleration due to gravity, and h is the height in meters.

Add the two known measurements together, then multiply by 2 - and you'll have your answer !
The negative sign in the formula for gravitational potential energy is used to signify that the potential energy is defined as zero at an infinite distance from the gravitational source. It allows for the interpretation that as objects move closer together, their potential energy decreases and is considered negative in relation to the reference point.
When an object is lifted to a higher position above the ground, its gravitational potential energy increases. When an object falls from a higher position to a lower position, its gravitational potential energy decreases due to the conversion of potential energy to kinetic energy. When two objects move closer together due to gravitational attraction, their gravitational potential energy decreases as they come to a shorter separation distance.

Potential energy depends on mass and height because mass determines how much an object can be affected by gravity, while height affects the distance the object can potentially fall. Together, mass and height contribute to the gravitational potential energy stored in an object due to its position in a gravitational field.
The sun primarily has potential energy due to the gravitational forces that hold it together. This potential energy is released as heat and light energy through nuclear fusion reactions occurring in its core.
