Answer:
Length of the flag is 190 feet and width of the flag is 80 feet.
Step-by-step explanation:
Given:
Perimeter of the flag = 540 feet
We need to find the length and width of the flag.
Let the length of flag be 'l'.
Let the width of the flag be 'w'.
Now given:
length is 110 feet greater than the width
Length of the flag
Now we know that,
Flag is in rectangular shape.
So Perimeter of rectangle is given by 2 times sum of length and width.
framing in equation form we get;
Now dividing both side by 2 we get;
Now Substituting the value of 'l' in above equation we get;
Subtracting both side by 110 we get;
Dividing both side by 2 we get;
Width = 80 feet
Length
Hence Length of the flag is 190 feet and width of the flag is 80 feet.
"x" represents an unknown number, we know that 70% of x equals 63.
To calculate the percentage of a number you have to multiply the said number by the percentage, in this case, 70%, and divide the result by 100:
So the 70% of x can be calculated as:
You can simplify this expression by solving the division
Then the expression that shows you the relationship is
Using this expression you can determine the value of x, to do so you have to divide both sides of the equal sign by 0.7
The value of x is 90
