Given that the width of the rectangular piccture is:
Where "l" is the length of the picture.
You know that the perimeter is:
The formula for calculating the perimeter of a rectangle is:
Where "l" is the length and "w" is the width.
Therefore, you can substitute the perimeter and the width into the formula, in order to find "l":
Now you can solve for "l":
Hence, the answer is:
Answer:
2 times
Step-by-step explanation:
1/3=.33 and 3/4=.75,so .33*2 is .66,which is still smaller than .75
Mark me brainliest if this helped :D
Decibel is directly proportional to number of cars passing the point. That is,
69 db ----- 139 cars
x db ----- 17 cars
x = number of cars passing the point per minute on a weekend.
Then,
x= (69*17)/139 = 8.43 db ≈ 8 db
The area is 210 square millimeters
