15√2
area = s² = 450 ← s is length of side
to find s take the square root of both sides
s = [tex]\sqrt{450}[/tex] = [tex]\sqrt{2(9)(25)}[/tex]
= √2 × √9 × √25 = √2 × 3 × 5 = 15√2
15√2 represents a side length of a square that has an area of 450 square inches.
The answer is option A.
The area of any quadrilateral can be determined by multiplying the length of its base by its height.
area = s² = 450 ← s is length of side
to find s take the square root of both sides
s = √450 = √2(9)(25)
= √2 × √9 × √25 = √2 × 3 × 5 = 15√2
Since we know the shape here is square, we know that all sides are of equal length. From this, we can work backward by taking the square root of the area to find the length of one side.
