For this case we have to:
w: Represents the width of the rectangle
L: Represents the length of the rectangle
Then, the perimeter is given by:
![P = 2w+2L](https://tex.z-dn.net/?f=P%20%3D%202w%2B2L)
According to the statement we have:
![L = 3.5+w\\P = 58](https://tex.z-dn.net/?f=L%20%3D%203.5%2Bw%5C%5CP%20%3D%2058)
Substituting we obtain the given equation:
![2w+2 (3.5 +w) = 58\\2w+7+2w = 58\\4w+7 = 58\\4w = 58-7\\4w = 51\\w = \frac {51} {4}\\w = 12.75](https://tex.z-dn.net/?f=2w%2B2%20%283.5%20%2Bw%29%20%3D%2058%5C%5C2w%2B7%2B2w%20%3D%2058%5C%5C4w%2B7%20%3D%2058%5C%5C4w%20%3D%2058-7%5C%5C4w%20%3D%2051%5C%5Cw%20%3D%20%5Cfrac%20%7B51%7D%20%7B4%7D%5C%5Cw%20%3D%2012.75)
Thus, the width of the rectangle is 12.75 feet
Answer:
The width of the rectangle is 12.75 feet
Answer:
Step-by-step explanation:
Distance traveled by Mike in 12 hours = 4 * 12 = 48 km
This will become the radius of the circle
r = 48 km
Area of the circle to be searched = πr²
= 3.14 * 48 * 48
= 7234.56 square km
Answer:
r = 8 ft
Step-by-step explanation:
Calculate r using the given formula
r =
, with Area = 64π
r =
← cancel π on numerator/ denominator
r =
= 8
