The given dimensions that we have in this question are 105 and 45
<h3>How to solve for the dimensions</h3>
We have 2(l + b ) = 300
l + b = 300/2
l + b = 150 ----- 1
The fencing would be
30l + (6b + 6b) = $3690
30l + 12b = 3690 ---- 2
We have to solve this through the use of simultaneous linear equation
The calculator that has been used to solve this is the simultaneous linear equation calculator.
This would give us the values of 105 and 45.
We have to conclude that the dimensions are 105 and 45

Answer:
why
Step-by-step explanation:
Answer:
Jeremiah travels at 26.667 mi/hr and Ermias travels at 18.667 mi/hr.
Step-by-step explanation:
Say Ermias' speed is 's' and Jeremiah's is 'v'
distance = rate * time
distance = ( v * time) + ( s * time)
v = s + 8
240mi = ( (s+8) * 8 ) + ( s + 8)
240 = (8s +64) + s + 8
240 = 9s + 72
240 - 72 = 9 s
168 = 9 s
18.6666667 = s
v = 18.6666667 + 8
v = 26.6666667
The area is a sector of circle that is 1/4 of 14-cm radius circle.
A = 1/4 * pi * r^2
A = 1/4 * 3.14 * (14 cm)^2 = 154 cm^2
