Width = 10 feet
Length = 40 feet
================================================
Explanation:
W = width
L = 4W = four times the width = length
P = perimeter
P = 2*(W+L)
P = 2*(W+4W)
P = 2(5W)
P = 10W
The perimeter is 100 feet.
P = 100
10W = 100 .... plug in P = 10W
W = 100/10 .... divide both sides by 10
W = 10
The width is 10 feet.
L = 4W
L = 4*10
L = 40
The length is 40 feet.
-----------------
Check:
P = 2(L+W)
P = 2(40+10)
P = 2(50)
P = 100
or another way to check is to add up the four sides {10, 40, 10, 40}
10+40+10+40 = 50+50 = 100
This confirms the answer.

Answer: 1.41 hours
<u>Step-by-step explanation:</u>
Geoff: 2.5 hours = 1 job
Max: 3.25 hours = 1 job
Together: ![\frac{x}{2.5} + \frac{x}{3.25} = 1 job](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B2.5%7D%20%2B%20%5Cfrac%7Bx%7D%7B3.25%7D%20%3D%201%20job)
⇒ ![(3.25)(2.5)\frac{x}{2.5} + (3.25)(2.5)\frac{x}{3.25} = (3.25)(2.5)1](https://tex.z-dn.net/?f=%283.25%29%282.5%29%5Cfrac%7Bx%7D%7B2.5%7D%20%2B%20%283.25%29%282.5%29%5Cfrac%7Bx%7D%7B3.25%7D%20%3D%20%283.25%29%282.5%291)
⇒ 3.25x + 2.5x = 8.125
⇒ 5.75x = 8.125
<u>÷5.75 </u> <u> ÷5.75 </u>
x = 1.413
