area is a vector quantity,no doubt - 100% sure read the portion of cross products from any of these:

i m a student of class 11
i was also not able to understand why area is a vector quantity
but after reading d above i understood
clear your concept by reading theory then jump into questions

hopin d above infor wil b helful 2 u
What else can I help you with?
How the area is vector and volume is a scalar?
Area is NOT a vector.
What is vector field?
A vector field is a mathematical construct that assigns a vector to every point in a space, often used in physics and engineering to represent quantities that have both magnitude and direction, such as velocity or force. In a two-dimensional space, for example, a vector field can be visualized as arrows of varying lengths and orientations across a plane, indicating how these quantities change over that area. Vector fields can be analyzed to understand flow patterns, gradients, and other dynamic behaviors in various contexts.
Is area a derived quantity?
Yes, area is a derived quantity.
What is the physical quantity of area?
The physical quantity is simply called area. The official unit (in SI) is the square meter.
What is curl in mathematical terms?
Curl represents the force of rotation in a 3-D vector field. Generally, the curl vector at a given point is the answer to the question, "What would happen if I stuck something there that could spin but couldn't move?" Unless the curl is zero, it would spin perpendicularly to the curl vector (according to the right-hand rule), and the longer the vector is, the faster. Curl is mathematically defined in a given direction as the limit of "circulation over area", i.e. the line integral of a circle around the point, divided by the area of the circle, with the circle shrinking towards the point. More practically, the actual vector can found by taking the cross product of the gradient operator with the function that defines the field: curl_x = ∂F/∂y - ∂F/∂z curl_y = ∂F/∂z - ∂F/∂x curl_z = ∂F/∂x - ∂F/∂y
Can a scalar quantity be made into a vector quantity by adding a direction to its magnitude why or why not?
Yes this happens in case of area. Usually area is a scalar quantity. But we provide the direction of course perpendicular to its plane area we make it as a vector. Same way though electric current is not a vector it is sensed as vector as we put along with length of conductor. I is scalar but Idl is vector.
Is pressure scalar or vector quantity?
Pressure is a scalar quantity. It is defined as the force per unit area and only has magnitude, not direction.
Why is area a vector quantity whereas its clearly a scalar quantity?
because i answered in my paper.
Is area scalar or vector quantity?
area is scalar.because we will not say that your area in this direction and my area in this direction . so,area has only magnitude Answer2: the product of two displacements produce a vector area, AxB this is a vector area. BxA is an opposite area.
Is electric flux a scaler or vector quantity?
Electric flux is a scalar quantity, as it represents the amount of electric field passing through a given area. It does not have a direction associated with it, unlike vector quantities.
Is area a vector or a scalar quantity?
it's a rather puzzling idea, but area can be either a scalar or vector quantity. Usually area is a scalar quantity. E.g. the area of my house is 2000 square feet. In more advanced calculus courses you'll run into area vectors. area is a vector because as u know pressure=force/area which is scalar"pressure"=vector"force" / X"area" area"X"= force/pressure which is vector/scalar =vector so area is a vectorIn geometry, for a finite planar surface of scalar area S, the vector area : is defined as a vector whose magnitude is S and whose direction is perpendicular to the plane, as determined by the right hand rule on the rim (moving one's right hand counterclockwise around the rim, when the palm of the hand is "touching" the surface, and the straight thumb indicate the direction). :
Is intensity of light scalar or vector quantity?
I think light could not be recoginzed as a vector. However, I think the light intensity could be devided into the x-y axises.
Is electric flux density scalar or vector?
Scalar
Is intensity of a wave a vector or a scalar quantity?
Intensity of a wave is a scalar quantity because it only has one value that represents the amount of energy transferred per unit area per unit time. It does not have a direction associated with it like a vector quantity.
Is current a vector or a scalar?
Definitely current is a SCALAR. Current density, of course, is a vector quantity Current = charge / time Both charge and time are scalars Current density = current / area Here area is a vector quantity Hence scalar product of current density and area give scalar quantity i.e. current. So electric current is a scalar Of course we assign +ve and -ve sign to currents. It is not because of direction as we do incase of vectors. But it is only algebraic sign.
How the area is vector and volume is a scalar?
Area is NOT a vector.
Area is scaler or vector quantity?
Well it is technically a vector because it has a magnitude and a direction on zero degrees. Reactive power will have a direction of either + or - 90 degrees and apparent power will be the vector sum of the real and reactive power.
