Answer:

l=20m

w=5m

Step-by-step explanation:

Let "l" be the length of the rectangle &

let "w" be the width of the rectangle

l=15+w

P=2(l+w)

50m=2(15m+w+w)

50m=2(15+2w)

50m=30m+4w

20m=4w

w=5m

l=15m+w

l=15m+5m

l=20m

Proof:

P=2(l+w)

P=2(15m+w+w)

50m=2(20m+5m)

50m=40m+10m

50m=50m

Step-by-step explanation:

Given

The attached function

Required

Determine the valid values of the domain of the function

To do this, we simply consider the starting point and the end point of the trajectory on the x-axis (i.e. the horizontal distance).

From the attached graph, the horizontal distance starts from 0 and ends at 180.

This implies that the domain is: 0 \le x \le 180

From the options, the values that fall in this bracket are 0ft and 60ft
