Hello : 
 the  <span>coordinates </span> circumcenter for ∆DEF : 
x = (1+7+1)/3
y = (1+1+5//3
x=3
y= 7/3
        
             
        
        
        
It gives the perimeter of 14 mm and if it is 3 mm tall, times that by 2 to get 6 for the total of both side then subtract 6 from 14 and you get 8 and then divide that by 2 
Answer is 4 mm wide for the two sides
        
             
        
        
        
Knowing that the area of a square is equivalent the square of its side length, the length of one side can be calculated by taking the square root of the area. The square root of the expression 9q^4r^8s^8 units is equivalent to <span>3q2r4|s3| units. When taking the square root of variables, the power they are raised to is divided by 2.</span>
        
                    
             
        
        
        
Answer:
51.26 ft
Step-by-step explanation:
First find the area of the triangle:
a=1/2 base times height
a=(1/2)(6)(4)
a=12 ft
Now find the area of the circles:
a= pi times radius squared
a= pi times 2.5 squared 
a=19.63 ft
19.63 + 12 = 31.63 ft
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Remark
Let the shorter base = x
Let the longer base = 3x
h = 5
Area = 60
Formula
Area = (b1 + b2)*h /2
Solution
60 = (x + 3x)*5 / 2                Multiply both sides by 2
2*60 = (x + 3x)*5                  Combine like terms
120 = 4x *5
120 = 20x                             Divide by 20
120/20 = x
x = 6
Therefore the two bases are
x = 6
3x = 18
