First, you factor and simplify (respectively) the numerator and denominator. Your equation becomes:

Notice, there is a (x + 7) on both the top and the bottom. Because of this, they cancel each other out. What is left is your answer:

Step-by-step explanation:
Answer:
- Length is <u>20 cm</u>
- Breadth is <u>10 cm</u>
Step-by-step explanation:
<h3>According to the Question</h3>
It is given that,
- Length of rectangle is twice as its breadth
- Perimeter of Rectangle = 60cm
We have to calculate the length and
breadth of the rectangle.
Let the breadth be x cm.
then,
Length be 2x cm.
Calculating the length and breadth-
- Perimeter of Rectangle = 2(Length+breadth)
By putting the value we get-
→60 = 2(2x+x)
→60 = 2(3x)
→60 = 6x
→x = 60/6
→ x = 10 cm
Since, breadth is <u>10</u> cm.
Therefore, Length = 2x = 2×10 = 20 cm.
- Hence, the length and breadth of rectangle is 20 cm & 10 cm respectively.
