Ruhi is pouring concrete to create the foundation of a square deck covering 112 square feet. Which is the best estimate of one side of the deck? Round to the nearest tenth, if necessary.
10 feet
10.3 feet
10.6 feet
11 feet
To find the length of one side of the deck, we need to find the square root of the area.
√112 ≈ 10.6
Therefore, the best estimate for one side of the deck is 10.6 feet.
To find the best estimate of one side of the deck, we need to calculate the length of one side of a square with an area of 112 square feet.
The formula to find the length of one side of a square is: side length = √(area)
Let's calculate the length of one side:
side length = √(112) ≈ 10.6 feet
Therefore, the best estimate of one side of the deck is 10.6 feet.
To find the best estimate of one side of the deck, we can use the formula for the area of a square, which is side * side.
Given that the area of the deck is 112 square feet, we can set up the equation:
side * side = 112
Rearranging the equation, we have:
side = √112
Calculating the square root of 112, we get:
side ≈ 10.583
Rounded to the nearest tenth, the best estimate of one side of the deck is 10.6 feet.
Therefore, the correct answer is 10.6 feet.
