The number of square tiles needed is 24 tiles
The formula for calculating the area of a rectangle is expressed as:
A = LW where:
L is the length
W is the width
For the rectangle:
Area = 12 feet × 8 feet
Area = 96ft²
For the square:
Area of a square = L²
Area of a square = 2²
Area of a square = 4ft²
Determine the number of square tiles that will cover the patio.
Number of square tiles needed = Area of rectangle/Area of square
Number of square tiles needed = 96/4
Number of square tiles needed = 24
Hence the number of square tiles needed is 24 tiles.

Answer:
y = 6 + 4x
After 4 years, the tree would be 22 ft tall.
Step-by-step explanation:
Hi there!
Let x = the number of years that pass
Let y = the height of the tree (ft)
We're given that the 6-foot tree grows at a rate of 4 ft per year. This means that the height of the tree will be equal to 6 ft, the original height, plus another 4 ft every year that passes.
Height of tree = 6 feet + 4 feet × number of years that pass
y = 6 + 4x
To solve for how tall the tree would be 4 years after Dina plants it, replace x with 4, since 4 years have passed:
y = 6 + 4(4)
y = 6 + 16
y = 22
Therefore, the tree would be 22 ft tall.
I hope this helps!
