Answer:

Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>let's solve:</h3>
we are given the formula,Mass and volume
to find density we just need to substitute the value of mass and value and simplify it


now we will use
to simplify division

hence, our choice is 
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.
Answer:
16 and 21/44 or 725/44
Step-by-step explanation:
convert 6 and 1/4 into an improper fraction; 25/4
convert 2 and 7/11 into an improper fraction; 29/11
multiply them together.
× 
you can do 25 × 29 to get 725
you can also do 4 × 11 to get 44.
725/44 simplifies to 16 and 21/44.
