Perimeter is the sum of all a shapes sides.
with that in mind, we know a rectangle has four sides. with 2 pairs being the same.
The length as told is, 5 centimeters less than two times the width. Two times the width would be 2w and five less than that would be minus five. so the length is 2w - 5
now to find the perimeter we do two times the width + two times the length.
2w + 2(2w -5) = 80.
Distribute: 2w + 4w - 10 = 80
Add ten to both sides and combine the 2w & 4w:
6w = 90
Divide both sides by 6: w = 15.
with this we know the width is 15. to find length plug in 15 to the 2w - 5 equation.
2(15) - 5 = 30 - 5 = 25.
Slap on the units and width = 15 cm, length = 25 cm
Y1=-4
x1=6
y2=4
y1+y2=0
So he is just his x displacement from where he started, 6 miles.
The perimeter of the top of the basket is 20 in.

What is perimeter of square?</h3>
Perimeter of square is defined as addition the lengths of the square's four sides.
Diagonal = 6
Let, side of square = a
a²+a² = 6²
2a² = 36
a² = 18
a = 3√2
Perimeter of the square = 4 × side of square
Perimeter of the square = 4 × 3√2
Perimeter of the square = 12√2 ≈ 20 in
Hence, the perimeter of the top of the basket is 20 in.

Answer:
- 20 -5k = 4
- the LCM of the denominators is 10
Step-by-step explanation:
I find it convenient to do the problem in the reverse order: find the LCM, then distribute. That way, I'm not distributing a fraction.
The LCM of 2 and 5 is their product: 2·5 = 10. Multiplying the equation by 10 gives ...
5(4 -k) = 4
Now, distributing, we get ...
20 -5k = 4
