The dimension of the rectangle is 40meters by 20meters
<h3>What is the perimeter of a figure?</h3>
The perimeter of a figure is the sum of all the external sides of the figure
The formula for calculating the perimeter of rectangle = 2(l+w)
If the length is 20 meters longer than the width, then;
l = 20 + w
Substitute
120 = 2(20+2w)
60 = 20 + 2w
30 = 10 + w
w = 20 meters
Since l = 20 + w
l = 20 + 20
l = 40 meters
Hence the dimension of the rectangle is 40meters by 20meters

The larger gear will have turned through an arc equivalent in length to the smaller circle's circumference. Thus:
2πr(small) = r(large)∅
2π(2) = 8∅
∅ = π/2 = 90°
2.
The distance covered by the larger gear will be:
C = 2πr
C = 2π(8)
C = 16π
Per revolution, the smaller wheel covers:
C = 2πr
C = 2π(2)
C = 4π
Number of revolutions of smaller wheel = 16π / 4π
Number of revolutions = 4
Replacing x by 4 and y by 2, it is found that the value of the expression is of 8.
The expression given is:
We want to evaluate it for x=4 and y=2, hence, we replace x by 4 and y by 2, then:
The value of the expression is of 8.

10 Numbers
Step-by-step explanation:
You take $22,000.00 + $625.00= 22,625.00 (which is the sales tax)
Take $22,625.00 x .06=$1,357.50
Then take $22,625.00 + $<span>1,357.50 +$40.00 = $24.022.50</span>
