Answer 1

Which represents a side length of a square that has an area of 450 square inches?
I believe the answer you're looking for is 15√2 inches.

Answer 2

we know that

the area of a square is equal to

`A=b^(2)`

where

b is the length side of the square

so

In this problem

`A=450 in^(2)`

`A=b^(2) \\ b^(2)=450\\ b=√(450) \\ b=15√(2) in`

therefore

the answer is

length of a square is equal to
`15√(2) in`
