Answer:
New area: 12ft^2
Step-by-step explanation:
1/3 of 9 is 3
1/3 of 12 is 4
Area = l x w
so 3 x 4 = 12
 
        
             
        
        
        
Answer:
14
Step-by-step explanation:
21 divided by 3 =7   7 per 1/3 
7x2=14
 
        
             
        
        
        
The two equivalent equations are d₁= 2a/d₂ and d₂= 2a/d₁ , Option 2 and 5 is the right answer.
<h3>What is a Rhombus ?</h3>
Rhombus is a quadrilateral with all the sides equal to each other.
It is given that d₁ and d₂ are the lengths of the diagonals.
and Area = a
a = (1/2) d₁ * d₂
        d₁ * d₂ = 2a
        It can be written as 
         d₁= 2a/d₂
a = (1/2) d₁ * d₂
         d₂= 2a/d₁
Therefore Option 2 and 5 are the correct answer.
The options of this question are:
1.  d₁=2Ad₂
2. d₁= 2A/d₂
3. d₂= d₁/2A
4. d₁= 2A/d₂
5. d₂= 2A/d₁

26.74. I’m assuming you are asking what 70% of 38.20 is. 38.20 x 0.70 = 26.74
        
             
        
        
        
The value of x from the given diagram is 17
<h2>Vertically opposite angles</h2>
From the given diagram, m<2 and m<3 are vertically opposite since they form angles from the intersection of lines at the point X
Given that;
- m<2 = 4x + 2
- m<3 = 5x - 15
Equate both expressions to have:
m<2 = m<3
4x + 2 = 5x - 15
4x - 5x = -15 - 2
-x = -17
x = 17
Hence the value of x from the given diagram is 17.
