Answer:
Length of one string is 7 cm less than the length of second string. OR Length of second string is 7 cm longer than length of one string.
Step-by-step explanation:
Given : lengths of two strings are 10 centimeters and 17 centimeters.
To find : Describe how the lengths of these two strings compare.
Solution : We have given that
Length of one string =10 cm.
Length of second string = 17 cm
We can compare both length in many way
Length of one string is 7 cm less than the length of second string.
OR
Length of second string is 7 cm longer than length of one string.
Therefore, Length of one string is 7 cm less than the length of second string. OR Length of second string is 7 cm longer than length of one string.
The difference is that the second string is 7 centimeters longer.

The length and width of the rectangle is 12 feet and 5.5 feet respectively given that the area of a rectangle is 66 feet², and the length of the rectangle is 1 feet more than twice the width. This can be obtained by finding algebraic expression for length by assuming width to be b and solving the quadratic equation formed after substituting it in the formula of area of rectangle.
What is the formula of area of a rectangle?
Area of a rectangle,
A= l × b, where A is the area, l is the length and b is the width.
Find algebraic expression for length:
Let us assume that width of the rectangle is b.
Given that, length of the rectangle is 1 feet more than twice the width
⇒ l = 2b+1 is the required expression.
Calculate the length and width:
Given that A= 66 feet²
In the formula, A= l × b we can substitute the expression for length.
66=(2b+1)b
2b²+b=66
⇒ 2b²+b-66=0
The quadratic equation can be solved using splitting the middle term,
2b²+12b-11b-66=0
2b(b+6)-11(b+6)=0
(2b-11)(b+6)=0
b=11/2 or b= - 6
Taking positive value of b, b=11/2⇒b=5.5 feet
Substitute for length, l = 2b+1 = 2(11/2)+1=11+1 =12 ⇒l = 12 feet
Hence the length and width of the rectangle is 12 feet and 5.5 feet respectively given that the area of a rectangle is 66 feet², and the length of the rectangle is 1 feet more than twice the width.

w = n
l = 2n+1
w*l = 66
n(2n+1) = 66
2n^2 + n =66
2n^2 + n - 66 = 0
using quadratic equation
n = 11/2
width = 11/2 = 5.5
length = 11 + 1 = 12
