Answer:
yes a scalene right angle triangle can be found for 25 for area.
Also isosceles right triangle but none for equilateral triangle.
Explanation:
3 x 2 x 4 =25.2
3.5 x 2.5 x 5= 25
2.103 x 2.9 x 4.1 = 25
2.343 x 3.234 x 3.30 = 25
Also an isosceles right side triangle
2.7 x 2.7 x 3.43 = 25
No equilateral right side triangles can be found.
The decimals can not be larger than the hypotenuse for equilateral sides that equal 25 and 25/3 and you cannot use reoccurring decimals for angles and their sides.
25 is not a great number for squares as only 5 or 1 divide equally.
There are better numbers like 20, 40, 60, 18. 24, 36 etc. or 16.8
but for squares 9. 16. 25, 36 I would say 36 and 64 are better square numbers as they do not have any prime numbers that divide into it ie) like 9, 27 example where 3 x 3 x 3 is the only triangle that could be found without using decimal for an area of 27.
