a 2D figure you multiply the length by the height. in a 3d object you multiply the length times the width times the height or
Decide what type of shape the object is. This will determine the area formula that you will use.
Find the area of a square or rectangle by multiplying the length times the width. This formula looks like l*w. If the length is 5 and the width is 2, the area is 10 square units.
Calculate the area of a four-sided shape that is not a rectangle by multiplying the base (one of the sides) by the height. The height is a line drawn from the top of the shape to the base forming a right angle with the base. If the base is 10 and the height is 4, the area is 40 square units.
Find the area of a triangle by multiplying the base times the height and then dividing it by two. The base can be any side of the triangle, and the height is the measurement from that base to the vertex above it. This formula looks like (b*h)/2 or ½ b*h and is derived from the fact that a triangle is half of a four-sided shape. If the base is 10 and the height is 4, the area is 20 square units.
Determine the area of a circle by squaring the radius and multiplying it by pi, or 3.14. This formula looks like pi*r^2. If the radius is 5, the area is 78.5 square units.
Find surface area of a three dimensional shape by finding the area of each face separately using the above formulas, and then adding these areas together.

You need the area to find the volume of an object.
Mass = Pressure*Area
Pi x radius2 x height
If you were upholstering a couch, you'd want to know how much fabric to buy.

To find the area of a object you do width x highth for a rectangle. You multiply on side of the object 4 times to get the area of a square. To find the area of a trapizoid, the formula is, 1/2 times highth (base 1 plus base 2).
You need the area to find the volume of an object.
To find the the area of a shape is to find the space that is enclosed within a 2D object. Do not mix it up with volume, which is the space enclosed within a 3D object.
Mass = Pressure*Area
You multiply the two sides the object in order to find the square feet of an area
Perimeter is the distance around an object. Area is the total amount of space inside the object. Length is the the measurement of one side of the object. Length is added up to find the perimeter. Length is multiplied to find the area.
Calculus can be used to find the surface area of any object given that you know the equation describing said object. It's usually easier to find the area from experiment or through using a combination of existing models to approximate the surface area
Yes.
Its shape and dimensions
it depends on your object. if your object is a triangle the area in square units is .5base times hieght if your object is a circle the area in square units is pi time radius squared if your object is a rectangle the area in square units is length times width
