Step-by-step explanation:
Given:
The ratio of the area between a small square of land and a large square
of land is 3: 7.
Total area of the two squares of land (in sq. meter) is 4000.
Required:
The area of each square of land.
Answer:
We have the ratio of the area between a small square of land and a large square of land is 3: 7.
Let

be the area of the square of land.
Then their ratio is given by,

Also given that the total area of the two squares of land (in sq.meter) is
4,000.
The area of
Therefore,

Therefore,the area of small square (in sq. meter) is,

and the area of large square (in sq. meter) is,

Final Answer:
The area of small and large square respectively (in sq. meter) is,1200 and 2800.
Answer:
7
Step-by-step explanation:
Using the definition
n
= 
where n! = n(n - 1)(n - 2)..... 3 × 2 × 1
Then
7
=
=
← cancel out the multiples 6 ×5 × 4 × 3 × 2 × 1 , then
7
= 7
