Answer:
Andre has the correct answer. When simplified his answer is equivalent to the original equation.
Answer:
For covering unit area of the entire playground, the amount of sand required is equal to volume of buckets of sand.
Step-by-step explanation:
Given -
volume of sand in bucket is able to cover area of the entire playground
Thus,
For covering unit area of the entire playground, the amount of sand required is equal to of the total volume of sand in bucket
For covering unit area of the entire playground, the amount of sand required is equal to
For covering unit area of the entire playground, the amount of sand required is equal to volume of buckets of sand.
If the ratio of the dimensions is 4:7 and the shorter dimension is 10ft, we know that the 10ft corresponds to the 4 in this scenario. We can set up the equation as follows:
You have to multiply by 2.5 to get from 4 to 10. And since we want to make sure we are maintaining the ratio, we have to multiply the denominator, 7, by 2.5 as well.
This means your shorter side has a length of 10ft and your longer side has a length of 17.5ft.
AREA
The formula for the area of a rectangle is:
So we can plug our dimensions into the formula:
So 175 is our area. But we can't forget about units! Since this is area and we multiplied our units together, our units would be squared. That means our answer is <u>175 square feet</u>.
PERIMETER
The formula for the perimeter of a rectangle is:
We can plug our dimensions into the formula:
So 55 is our perimeter. Of course, we can't forget about our units. Because this is perimeter, we only added our units together, so they don't change. That means our answer is <u>55 feet</u>.
