B.w=160 ft, L = 100 ft
C.W = 40 ft, L = 100 ft
D.W = 100 ft, L = 160 ft

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem we have

Find the value of the constant of proportionality k

we have

For x=2, h=44

substitute

The linear equation is

so

For x=1.5

substitute the value of x in the linear equation and solve for h(x)
