Answer: 
P=32m
A=48 m^2
Step-by-step explanation: 
if two shorter sides are 4m each and the two longer sides are 12 m
4+4+12+12 to find the total P
Area, time the LENGTH by WIDTH to find the squared meters in the rectangle .
4x12 = AREA

Answer:
1) D
2) 10
Step-by-step explanation:
sin(30) = opposite/hypotenuse 
sin(30) = 5/x
½ = 5/x
x = 5/0.5
x = 10
 
        
             
        
        
        
Assuming that the cost per minute is the same for both months and the plan fee is the same, you can use y=mx+b for this
y is the cost of the phone plan, x is the cost per minute and b is the start cost.
so    19.41=25x+b for the first month
and  45.65=380x+b for the second month
solve both for b you get:
19.41-25x=b and 45.65-380x=b.  from this we get
19.41-25x=45.65-380x
solve for x
328x=26.24 and x=0.08
this means the cost per minute is 0.08c/min (answer A)
rewrite the equation to calculate b, and where this time, the x is the number of minutes talked.
y=0.08x+b and plug in one of the two months
45.65=0.08 * 380 + b
Solve for b and b is 15.25
so the final equation is
y=0.08x+15.25  (answer B)
