Answer:
w=10 feet
l=21feet
Step-by-step explanation:
let width be x
p=2l+2w
p=62
so we form the equation
l=1+2x
w=x
2(1+2x)+2(x)=62
2+4x+2x=62
6x=60
x=10feet
w=10feet
l=1+2x
l=21feet

Find P(A n B)
where
A = Event that the place is a city
B = Event that the place is in North
The first step is to get the sample space;
Let S represent the sample space;
The next is to list events A and B
A = City
B = North America
The next is to list common elements in A and B
The probability of A and B is calculated as follows;
Substitute and in the expression above
4+96=100 when you follow PEMDAS
