I wonder what shape the window is? It has a radius so I expect a circle but you use the word perimeter which is usually reserved for shapes with sides.
So my guess is you are looking for the circumference of a circular window with radius 20. The circumference is given by (pi)d where d is the diameter. The diameter is twice the radius so 40. We use 3.14 to approximate pi.
That makes the circumference (the distance around the circle) = (40)(3.14)=125.6
Answer:
first you would add 5 on both sides
then you should have 15y = 28
then you will divide 15 by 15
then do the same to 28

Answer:
6/5m
or
1 1/5m
Step-by-step explanation:
5 - 3 4/5 = x
5/1 - 19/5 = x
5/1(5/5) - 19/5 = x
25/5 - 19/5 = x
25/5 - 19/5 = 6/5
x = 6/5 or 1 1/5
