Answer:
The total distance around the canvas painting is 60 cm.
Step-by-step explanation:
The total distance around the canvas painting is 60 cm, we know this because, to find the perimeter of a square you add the length of all 4 sides together. To find the length of 1 side we take the square root of the area which is 196 cm², this equals 14 cm. To find the perimeter we add all 4 sides together, so 14+14+14+14=60 cm.
Answer:
n = 9
Step-by-step explanation:
20 + 18 + ... + 6 + 4
---------------------------
a = 20 ; d = -2 ; n = ?
--------
4 = 20 + (n-1)(-2)
-16 = (n-1)(-2)
---------
n-1 = 8
n = 9
-------
S(9) = (9/2)(20+4)
S(9) = 4.5*24
S(9) = 108
if we name that part x, then we can say
1/x = 1/a + 1/b
.503 is written as a decimal.
