Answer:
<h2>width = 6 feet</h2>
Step-by-step explanation:
let l be the length of the rectangle
let w be the width of the rectangle
The statement
The length of a rectangle is 6 feet more than three times the width of the
rectangle is written as
l = 6 + 3w
From the question
l = 24 feet
Substitute the value into the above formula and solve for the width
That's
24 = 6 + 3w
3w = 24 - 6
3w = 18
Divide both sides by 3
w = 6
Therefore
<h3>width = 6 feet</h3>

Answer:
area of circle=πr²=1.3mi²
we have
area of sector=∅/360×πr²
0.7mi²×360=∅1.3
∅=0.7×360/1.3=193.846°×π/180=387.7 radian
