You take the square root of the number. If it is a perfect square, this will be a whole number. If it is not, it isn't a perfect square.
51 is not a perfect square. 72 = 49 82 = 64 51 is between 49 and 64 so its square root is 7+a bit, and it is not a perfect square.

It is: 72/104 = 9/13 in its lowest terms
NO. 72 = 2 x 36 = 2 x 62 and 72 = 8 x 9 = 8 x 32 Some of the factors of 72 can be represented as perfect squares but not all the factors, hence 72 itself is NOT a perfect square number.

No because its square root is an irrational number
51 is not a perfect square. 72 = 49 82 = 64 51 is between 49 and 64 so its square root is 7+a bit, and it is not a perfect square.
The square root of 72 is an irrational number. Since 72 is not a perfect square, the decimal is endless. (just like the value of pi)
A perfect square has the condition that it must be any positive integer multiplied by itself. The closest perfect squares to 50 are 7*7 = 72 = 49 and 8*8 = 82 = 64 since 50 lies between 49 and 64, it must be it is not the square of a positive integer and, therefore, is not a perfect square.

To get the area you multiply the length and the width. Doing the math gives an answer of 72 square feet. Divide by 9 and you get 8 square yards.
It is a proper fraction and can be simplified to 25/36 whose square root is 5/6

no. 72 is not a square number.
