Question

lemon has to find the area of a rectangle. the area can be determined by the equation ( a = 8w ), where ( a ) is area and ( w ) is the width of the rectangle. what is the constant of proportionality?

Explanation:

Step1: Recall the formula for direct proportionality

The equation for direct proportionality is \(y = kx\), where \(k\) is the constant of proportionality.

Step2: Compare with the given equation

Given \(A = 8w\). Comparing with \(y = kx\) (here \(y = A\), \(x = w\)), we can see that \(k = 8\).

Answer:

\(8\)
