<h3>
Answer: 180 inches</h3>
Work Shown:
L = 54 = length
W = 36 = width
P = 2(L+W) ... perimeter of the rectangle
P = 2(54+36)
P = 2(90)
P = 180
She needs 180 inches of ribbon.
To convert to feet, divide by 12. So 180 inches = 180/12 = 15 feet.
I hope you actually want to know the number of fishes caught by Trenton the friend of Princeton. Let us write down all the details that are given in the question. These details will help in answering the question.
Number of fishes caught by Princeton = 42
Let us assume the number of fishes caught by Trenton = x
Then
70x/100 = 42
7x/10 = 42
7x = 42 * 10
7x = 420
x = 420/7
= 60
So the number of fishes caught by Trenton = 60.
First write the factors of 9:
9, 18, 27, 36, 45
Then look for ones that are greater than 20:
27, 36, 45
Hope this helps :)
