The function of the area of the square is A(t) = 49t².
A function is a relation between the input abd output values.
The length of a square's side starts from 0 cm and increases at a constant rate of 7 cm per second.
Let us assume that the function 'f' determines the area of the square (in cm²)
Also Lets the length of side of square is x
rate of change of length with respect to time can be denoted as (dx/dt) = 7 cm/sec
⇒ x = 7*t
Area of square = ( length of side )²
{as the length of side is 7t} {varies by time}
Area of square A(t) = ( 7*t )²
Therefore, The function of the area of the square is A(t) = 49t².
