Answer:
The required equation is 3y=36 and the tape diagram is shown below.
Step-by-step explanation:
Consider the provided information.
We need to write a multiplication equation that has a solution of 12.
3y=36
We know we have to split 36 into three equal groups, so we have to divide by 3 to show this algebraically.
3y÷3=36÷3
y=12
Now check this with the help of tape diagram as shown.
Consider the figure 1.
This represents if 36 had to be split into three groups, how big would each group be?
By the tape diagram we concluded that the value of y is 12.

Answer: THERE ARE TWO WAYS OF DOING THIS!!
Key words: square, area, 200 square feet
Area: what × what = 200?
Step-by-step explanation:
A square has 4 sides, and all of its sides are of equal length.
So if a square has 4 sides, and its total area is 200 square feet, what do you have to do?
You have to divide the area by 4!
So 200 ÷ 4 = ?
200 ÷ 4 =50
So each side is 50 feet long.
In this scenario, there are no tenths because each side is exactly 50 feet. If you wanted the lengths to the nearest tenth, your answer would be 50.0

If patio is a square, basically it says the area is where a is equivalent to one side of the square.
Now that we know that a = 200, we will be able to solve the expression
a=
a=14.1421, which is the square root of
Now we rounded to the nearest tenths
a≈14.1
We rounded to 14.1 because the rounding rule is: <em>4 and below rounds down, 5 and above rounds up.</em>
The result is 14.1
