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>.

Step-by-step explanation:
Answer:
6/4 or 1 1/4
Step-by-step explanation:
1/4 times 6 because the question is asking for the recipe to be made 6 times. So 1/4 times 6 or 1/4 time 6/1 is 6/4 or 1 1/4.
Answer:
If Lauren spend 2/3 of her 24-hour computer time doing homework, this means she spent 16 hours doing homework. Each third of the 24 hours is 8 hours, so two thirds would be 16 hours.
Answer:
The length of the office is 36.4 ft
Step-by-step explanation:
The length of the classroom = 20 ft long
The length of the office = 20 ft + 82% of the classroom length
Now, 82 % of classroom length = 82 % of 20 ft
⇒ 
or, 82% of 20 ft = 16.4 ft
⇒The length of the office = 20 ft + 16.4 ft = 36.4 ft
Hence, the length of the office = 36.4 ft
