Answer:
(P) =360
(l) =?
(b) =?
so, let the breadth be x
let the length be 2x
Perimeter of rectangle=2(l+b)
360 =2(2x+x)
360/2 =2x
180/2 =x
60 =x
x =60
ATQ
Breadth = 60
length= 60 ×2
=180
You would set up the problem like this: 3n-25=38
To solve for n:
3n-25=38
+25 +25 (Add 25 to both sides)
3n=63
/3 /3 (Divide by 3 on both sides)
n=21
The answer is 21.
By definition of conditional probability,
P(B | A) = P(A ∩ B)/P(A) = (13/25) / (13/20) = 20/25 = 4/5
The answer is b=2 because yea
