Answer:
about 14.142ft
Step-by-step explanation:
A square has four equal sides.
The area of a square: length * width = area
Because you know that all of the sides are equal, you can just say:
length * length = area
Multiplying a value (in this case, length) by itself is the same thing as squaring it. So, you can simplify the equation further by writing:
length² = area
Fill in what you know:
length² = 200ft²
Now, work the problem backwards by taking the square root of 200 to find the length:
√length² = √200ft²
length = 14.142ft
So, each wall is 14.142ft long
You can test this by working the problem in reverse:
14.142ft * 14.142ft ≈ 200ft²
261/18 = 14.5
So as a mixed number it would be 14 and 1/2
Answer: y = 4x
Step by step explanation:
If each tile is ¼ of a square foot then y (in terms of square feet) will be equal to x / 4 meaning that the equation would be y = 4x
Answer:
Step-by-step explanation:
One - third = 1/3
then:
one third of a number = a*1/3 = a/3
Then the equation that represents this sentence is:
2 + a/3 = 8
process:
a/3 = 8 - 2
a/3 = 6
a = 6*3
a = 18
Check:
2 + 18/3 = 8
2 + 6 = 8
