Final answer:
The length of one side of Natasha's square backyard, with an area of 625 square yards, is 25 yards.
Step-by-step explanation:
The question at hand is a problem related to finding the length of a side of a square given the area. Natasha is seeding her backyard, which is a square with an area of 625 square yards. To determine the length of one side of Natasha's backyard, we need to find the square root of the area since the area of a square is given by the formula Area = side × side, or Area = side2. Therefore, the length of one side is the square root of 625.
√625 = 25
Thus, the length of one side of Natasha's backyard is 25 yards.
