usually in a quadrilateral (four-sided shape) you multiply the height by width
In a triangle, the height by width then divide by 2. This is because a triangle is mathematically always half the area of the rectangle.
In a trapezium or trapezoid in some countries, its the top length added to the bottom length which is then divided by two multiplied by the length top to bottom. But always remember the height you multiply it with is the straight top to bottom length not the side length.
A=lw or a different formula depending on the object
A flat round object is a circle. Surface area of a circle = pi*radius squared.

By integration, which basically means dividing the object into small pieces.
To calculate the area in square centimeters of a two-dimensional object, you multiply the length and width of the object in centimeters. The formula for calculating the area of a rectangle or square in square centimeters is length (cm) x width (cm). For more complex shapes, you can break them down into simpler shapes and calculate the area of each part separately before adding them together to find the total area in square centimeters.

lenght x breadth
A flat round object is a circle. Surface area of a circle = pi*radius squared.
To calculate the force exerted on an object in a well flowing at a given rate, you can use the formula: Force = Pressure x Area. First, calculate the pressure at the depth of the object in the well using the fluid's density, gravity, and depth. Then, determine the cross-sectional area of the object to which the pressure is being applied. Multiply these values to find the force exerted on the object.
To find the position of an object from a velocity-time graph, you need to calculate the area under the curve of the graph. This area represents the displacement of the object.

By integration, which basically means dividing the object into small pieces.
To calculate the area, we divide the force (1500 N) by the pressure (500 Pa) to get an area of 3 square meters. For the second part, if we double the area to 6 square meters and keep the force constant at 1500 N, the pressure would be halved to 250 Pa over the new larger area.
To calculate the area in square centimeters of a two-dimensional object, you multiply the length and width of the object in centimeters.

The question does not specify of what object the curved surface area is required. Without this information then a meaningful answer cannot be provided.
To find the position of an object from a velocity vs. time graph, you need to calculate the area under the velocity vs. time curve. This area represents the displacement of the object.
To calculate pressure, you need to know the force applied on an object and the surface area over which the force is distributed. Pressure is calculated by dividing the force by the surface area.
