A trick for figuring out squares of larger numbers that is sometimes helpful: if you can write the numbers as the product of two different numbers, then you can square those two numbers and multiply that to find the square of the original. 602 = 102*62 = 100*36 = 3600
70
64 = 28 + 36
yes because square numbers have to be hole numbers to be square
60" x 60" is about 2.3 square meters.

The only square number of an integer between 60 and 70 is 64, which is 8 squared.
36, 49
Square numbers have an odd number of factors. There are no square numbers in that range.
the two square numbers that make 65 are 16 (4x4) and 49 (7x7)
The four possible answers are +/- 18 or +/- 22.
70
Multiply the two numbers and you get 1,800 square inches. Each square foot has 144 square inches. So you get 12.5 square feet.
All but the square numbers - 53 of them.
The square root of 60 lies between 7 and 8 because 7 squared is 49 and 8 squared is 64 and 60 is in between 49 and 64.
