Answer:
It could be
Step-by-step explanation:
The calculation of sides of a rectangular triangle can be done by applying the Pythagorean theorem (the sum of the squares of the legs is equal to the square of the hypotenuse), both legs must form a right angle, and the value of the hypotenuse must be different from the legs. In the example what you give could be a value of one leg and the other of the hypotenuse.
Here, we know, √225 = 25 (perfect squared)
whereas √223 is not a perfect squared.
So, √225 would be "Rational" whereas √223 would be "Irrational" by the nature.
Hope this helps!
Answer:
581 m²
Step-by-step explanation:
The area of a trapezoid is determine as the average between the length of both bases T and B (46 and 37 m) multiplied by the height H. The area is:

Assuming that enough turf must be bought to cover the whole extension of the field, the amount of turf that should be purchased is 581 m².
A function is a process or a relation that associates each element x of a set X to a single element y of another set Y.
A. The equation
represents vertical line. This is not a function, because one element x=5 is associated to all (not one) elements of 
B. The equation
represents parabola that goes in positive x-direction. This is not a function, because each
is associated to two different y. For examlpe, when x=10, then 
C. The equation
represents parabola that goes in positive y-direction. This is the function, because for each x is associated only one y.
D. The equation
represents hyperbola. This is not a function, because for one x there are two different possible y.
