Let the width be x
width = x
length = 2x - 3
Perimeter = x + 2x - 3 + x + 2x - 3 = 6x - 6
6x - 6 = 78
6x = 78 + 6
6x = 84
x = 14 cm
2x - 3 = 2(14) - 3 = 25cm
The width is 14cm and the length is 25cm
Answer: The experimental probability that she will roll an even number= 
Step-by-step explanation:
We know that the probability for any event is given by6;-

In a dice, the total even numbers (2,4,6)= 3
Therefore, the probability that she will roll an even number will be given by:-

Hence, The experimental probability that she will roll an even number= 
Answer:
Step 3 contains error.
