Answer:
Length of the Rectangle = 10 inches
and Width = 25 inches
Step-by-step explanation:
Let the width of the rectangle = k inches
So, the Length of the rectangle = (3k - 5) inches
Perimeter = 70 inches
Now, Perimeter of the Rectangle = 2(Length + Width)
= 2 (k + (3k-5))
⇒ 2 (k + (3k-5)) = 70
or, 2(k + 3k -5) = 70 ⇒ 2(4k - 5) = 70
⇒ 8k - 10 = 70
or, 8k = 70+ 10 = 80
or, k = 80/8 = 10
So, the Length = 10 inches
Hence, Width = 3k - 5 = 3(10) - 5 = 30 - 5 = 25 inches
So, Length of the Rectangle = 10 inches
and Width = 25 inches
Thank you for posting your question here at brainly. Below ist he answers:
a. T= d/r
b. It's reasonable to write distance as a positive number because distance is always positive. You are not able to have a negative distance. Imagine someone standing on a side walk. Even if they are not moving, their distance is 0 which is positive. If they move backwards or forwards, their distance is still positive because it is more than that 0 and they are gaining something.
c. T= d/r
T= 32.12 m /<span>8.8 m/min
T= 3.65 min
