Answer: 18 cm^2
Step-by-step explanation:
There are four equal triangle and a rectangle.
Formula of a rectangle = b * h = 2*3 = 6
Formula of triangle =   but there four of them so we times them by 4, this leaves us with 2 (b * h) = 2(2*3) = 12
 but there four of them so we times them by 4, this leaves us with 2 (b * h) = 2(2*3) = 12
Area of pentagon = area of all triangles + rectangle 
Area of pentagon = 12 + 6 = 18
Hope this helps.

Answer:
4/10 or 2/5
Step-by-step explanation:
9/10-1/2 = 9/10-5/10 = 4/10 = 2/5
 
        
                    
             
        
        
        
Find out what half of 39° (angle ABD) Then subtract that from 180° (angle ABE). When the plain flus faster angle (ABD) gets smaller and angle (ABE) gets bigger. Hope that helps.
 
        
        
        
Invested amount (P) = $300.
Time in years (t) = 2 years.
Balance after 2 years (A) = $329.49.
Let us assume rate of interest = r % compounds annually.
We know, formula for compound interest 

Plugging values in formula, we get




Taking square root on both sides, we get 





r=0.048.
Converting it into percentage by multiplying by 100.
r=0.048 × 100
r  = 4.8 %
Therefore, the rate of interest on the account is 4.8% compounds annually.
