This is a particular case, but it is not necessarily true. If triangles STU and XYZ are similar, the corresponding sides are in the same proportion. So, there exists a number 
such that
So, if 
, the corresponding sides are actually congruent, but it can be any other number. For example, if 
, triangle XYZ is exactly twice as large as triangle STU, but they are still similar.

64+36+30+80= 210 yards sq, because you break up the playground into squares and rectangles then multiply the with times length. For the slanted part, you create it into a square and use the yd from the other sides of the playground.
Answer:
Option D i.e. y = 1/2 x is the correct answer.
Step-by-step explanation:
We know that when 'y' varies directly with 'x', we get the equation
y ∝ x
y = kx
where k is the constant of proportionality.
In our case, the only equation which maps in accordance with y = kx is y = 1/2x.
i.e.
y = 1/2 x
here k = 1/2
Thus, k = 1/2 is the constant of proportionality.
Therefore, option D i.e. y = 1/2 x is the correct answer.
Answer:
A. 450
Step-by-step explanation:
180 is 40% of the original
450*0.4=180
298*0.4=119.2
240*0.4=96
72*0.4=28.8
so A. 450 is correct
