That depends on what measurements are used
25 square yards in a 15' x 15' room.
25' x 15' = 375 square feet.
The least common denominator of 25, 15, and 3 is 75. To get this we need to find the smallest number that is divisible by 25, 15, and 3 without any remainders. Since 25 has to go into the number it is easiest to first look at which numbers are divisible by 25 without any remainder. This would be numbers like 25, 50, 75, 100, etc. Then look at which of these numbers are divisible by 15 and 3 without any remainder. The first number that is is the least common denominator. In this case, it is 75.
15 goes into 25 1.66... (recurring) times.
The least common denominator of 25, 15, and 10 is 150. To get this we need to find the smallest number that is divisible by 25, 15, and 10 without any remainders. Since 25 has to go into the number it is easiest to first look at which numbers are divisible by 25 without any remainder. This would be numbers like 25, 50, 75, 100, etc. Then look at which of these numbers are divisible by 15 and 10 without any remainder. The first number that is is the least common denominator. In this case, it is 150.
5,5 25
The diagonal is 25 feet.
There are 3 feet in 1 yard so 15 feet is equal to 5 yards. So a 15 feet by 15 feet room is a 5 yard by 5 yard room. 5 yards x 5 yards = 25 square yards.
