You can write an equation.
KL+LM=KM
Enter the info
x+.5+3x-2=3x+1.5
Combine like terms
4x-1.5=3x+1.5
Add 1.5 to both sides
4x-1.5+1.5=3x+1.5+1.5
4x=3x+3
Subtract 3x from both sides
4x-3x=3x+3-3x
x=3

Then, enter 3 into the expression to find LM
3x-2
3(3)-2
9-2
7
LM is worth 7.
I hope this helped!

Answer:The height of the pharmacy area is 17 feet

Step-by-step explanation:

The formula for determining the area of a rectangle is expressed as

Area = length × width

The pharmacy area is rectangular. The height of the pharmacy area becomes the width of the rectangle.

The area of the pharmacy area is given as 391 ft^2

The length of the pharmacy area is given 23 feet

Therefore

23 × h = 391

h = 391/23 = 17 feet
