The constant of variation, k, is equal to 108. This is an inverse proportion and when L is 27 cm, W is 4 cm
An equation is an expression that shows the relationship between two or more numbers and variables.
The length (L) is inversely proportional to the width (W), hence:
L = k/W
18 = k/6
k = 108
When L = 27:
27 = 108/W
W = 4
The constant of variation, k, is equal to 108. This is an inverse proportion and when L is 27 cm, W is 4 cm
