Answer:
√20 units. 
Step-by-step explanation:
Please see attached photo for diagram. 
The other leg of the triangle is x as shown in the attached photo. 
Using the pythagoras theory, we can obtain the the value of x as follow:
x² = 4² + 2²
x² = 16 + 4
x² = 20
Take the square root of both side. 
x = √20 units 
Therefore, the value of the other leg x of the triangle is √20 units 
 
        
             
        
        
        
Since you have parentheses, you will first multiply (q-2)*(r-3) which equals (qr+6). So now its simplified to p(qr+6) which equals pqr+p6.
