Answer:
9×13=117, The rectangle is 117cm
Step-by-step explanation
The formula for a rectangle is L*W
A circle is 360° all the way around; therefore, if you divide an arc's degree measure by 360°, you find the fraction of the circle's circumference that the arc makes up. Then, if you multiply the length all the way around the circle (the circle's circumference) by that fraction, you get the length along the arc.
Answer:
(12 nickels))
(5 dimes)

Based on the information given in the problem, you can set up the following system of linear equations, where:
x: number of nickels.
y: number of dimes.
Then
FIRST EQUATION: 
SECOND EQUATION:
(in cents)
You can apply the Substitution method:
- Solve for x from the first equation.
- Substitute into the second equation and solve for y.
Then:


- Find x:
