Answer: L = 29cm
Step-by-step explanation:
Let's go!!
To find any rectangle area, you have to apply this formula: A = L . w , where L is the length and w is the width.
So, we have w = L - 13 (the width is 13 less than the Length) and then, perimeter is 90 cm.
Well, I hope you remember that the perimeter of rectangle is 2L + 2W. In this case, 2L + 2w = 90
Then, you might to solve this system of equation:
2L + 2w = 90
w = L - 13
Simplifying the first equation, you'll have L + w = 45 (you can divide everything of 2).
Our new system:
L + w = 45
w = L - 13
Using the substituition method:
L + L - 13 = 45
2L = 58
L = 29 cm
the width is 29 - 13 = 16 cm

Answer:
The answer is 602/45
Step-by-step explanation:
Since this involves subtracting fraction, we must make sure each denominator is alike, which involves find the LCD (least common denominator).
9, 5, and 1 (the number 14's denominator is 1) all have the LCD 45 in common.
Multiply 9 by 5, which multiplies 2 with 5, giving 10.
Multiply 5 by 9, which multiplies 2 by 9, giving 18.
Multiply 1 by 45, which multiplies 14 by 45, giving 630.
Now, you have an equation that looks like this:
(630/45) - (10/45) - (18/45)
Subtract 10 from 630, which gives 620, then subtract 18 from 620, giving 602.
Final answer: 602/45
