The functions=Acan be used to find the length of a side of a square given its area. Use this function to determine the length of a side of a square with an area of 90 square inches. Round to the nearest tenth if necessary.

Short Answer

Expert verified

The length of a side of a square with an area of 90 square inches rounded to the nearest tenth is 9.5inches.

Step by step solution

01

Step 1. Write the relationship between the length of a side of a square and the area of the square.

The relationship between the length of a side of a square and the area of the square is:

s=A, where s is the length of a side of a square and A is the area of the square.

02

Step 2. Determine the length of a side of a square.

It is given that the area of the square is 90 square inches. Therefore, the value of A is 90.

Substitute 90 for A in s=A.

s=A=90=9脳10=32脳10=310=33.16227766=9.48683298鈮�9.5

Step 3. Conclusion

Therefore, the length of a side of a square with an area of 90 square inches rounded to the nearest tenth is 9.5 inches.
