To find the area of something you have to multiply the length x the with x the height. Or if it gives to the base then you multiply the base x the height.
Answer:
Potential energy is energy due to an object's height above the ground.
Potential energy = mass x gravity x height
Kinetic energy is energy due to the motion of the object.
Kinetic energy = 1/2 x mass x velocity²
