the length of a rectangle is five times its width. if the area of the rectangle is 245 meters squared, find its perimeter
Vikentia [17]

Your answer is 84 meters.


We can call the width x, and thus the length 5x, and then we can say that 5x × x = 245, which simplifies to 5x² = 245, and then we can solve:


5x² = 245

÷ 5

x² = 49

√

x = 7


Now that we know what x is, we can find the perimeter by using it as the width, and then multiplying it by 5 to find its length. This gives us:


(7 × 2) + (5 × 7 × 2) = 14 + (35 × 2) = 14 + 70 = 84


So your answer is 84 meters.


I hope this helps!

dezoksy [38]

The rated speed of the access point = 2 GB/sec.

The throughput is half the rated speed = 1 GB/sec.

1 GB/sec. = 1000 MB/sec.

Each person downloading is getting an average of 200 MB/sec.

<u>So, the number of people are using the internet at that moment = 1000/200 = 5 persons.</u>
