Answer:
The answer is option B
Explanation:
To find the constant in the equation pick any values of x and y and substitute it into the equation
First make constant the subject
constant = height × width
From the question
Using
height = 30
width = 2
We have
constant = 30 × 2 = 60
Again
Using
height = 12
width = 5
constant = 12 × 5 = 60
Since the constant is the same for any values used
constant = 60
Hope this helps you
