Answer:
a = 10 cm
Step-by-step explanation:
Area of triangle, A = 51 cm²
base, b = 10.2 cm
Let height of triangle be a cm
<em><u>Formula:-</u></em>




hence, the missing length is 10 cm
The coordinates for point a are (-3,5)
The first point tells you the x value and the second tells the y value

I think 20/50 is the answer you're looking.
Answer:factor of 9
Step-by-step explanation:
Given
prism were changed by a scale factor of 3
Suppose prism is rectangular in shape
So surface are is 
Where l=length
w=width
b=breadth
So new length,breadth and width is






So new surface area would change by a factor of 9
The answer is 10√3 because
10√3 is equal to approximately 17.32051 and the formula for finding the area of a square is length multipled by width so 10√3 x 10√3 is equal to 300 or 17.32051 x 17.32051 is equal to 300
