Answers
Joint variation equation is a situation when the final value varies by two or more variablesEquation 1A = s²Here we have only one variable, 's', and the value of Area will only vary when s varies.Equation 2A = πr²Here the only variable is 'r', which is the radius of a circle. The value of Area, A, varies as radius varies. π is a constant.Equation 3A = l×wHere we have to variables, the 'l' and the 'w'. We can say that the value of Area, A, will vary jointly as l and w varyThe correct answer is option a)
