Answer:

Step-by-step explanation:
Let the length and breadth be 5x and 4x respectively.
Area of rectangular field = 18000 m²
<u>Finding </u><u>the </u><u>value </u><u>of </u><u>x</u>
Area of rectangle = 
Plug the values
⇒
Calculate the product
⇒
Swap the sides of the equation
⇒
Divide both sides of the equation by 20
⇒
Calculate
⇒
Squaring on both sides
⇒
<u>Replacing the value of x in order to find the value of length and breadth</u>
Length = 
Breadth = 
<u>Finding </u><u>the </u><u>perimeter</u><u> </u><u>of </u><u>the </u><u>rectangular</u><u> </u><u>field</u>
Perimeter of rectangle = 
plug the values
⇒
Distribute 2 through the parentheses
⇒
Add the numbers
⇒
Hope I helped !
Best regards!!
7844=7400(1+(8/12)r)
Solve for r
R=0.09*100=9%
Desk is $600
chair is $120
cost of chair x 5 = cost of desk
600 + 120 = 720
The answer will be 17 tons.
Step-by-step explanation:
Since we have given that
14 T 1,000 lb. + 2 T 1,000 lb.
As we know that

So, 14 T 1,000 lb. is given by

Similarly,

so,
2T 1,000 lb. is given by

So, 14 T 1,000 lb. + 2 T 1,000 lbs is given by

Hence, the answer will be 17 tons.
