FAQs on 11 things you must know about Squares - Learn Maths Video Lecture
| 1. What is a square? |  |
Ans. A square is a shape with four equal sides and four equal angles. It is a regular quadrilateral and a special case of a rectangle where all sides have the same length.
| 2. How do you find the area of a square? | |
Ans. To find the area of a square, you multiply the length of one side by itself. The formula for the area of a square is A = s^2, where A represents the area and s represents the length of a side.
| 3. What is the perimeter of a square? | |
Ans. The perimeter of a square is the total length of all its four sides. Since all sides of a square are equal, you can find the perimeter by multiplying the length of one side by 4. The formula for the perimeter of a square is P = 4s, where P represents the perimeter and s represents the length of a side.
| 4. How can you determine if a shape is a square? | |
Ans. A shape is a square if it has four equal sides and four equal angles. You can measure the length of all sides and check if they are the same. Additionally, you can measure the angles to see if they are all right angles (90 degrees). If both conditions are met, the shape is a square.
| 5. Can a square be a rectangle? | |
Ans. Yes, a square can be considered a special case of a rectangle. A rectangle is a quadrilateral with opposite sides that are equal in length and all angles measuring 90 degrees. Since a square has all sides equal in length and all angles measuring 90 degrees, it meets the criteria to be classified as a rectangle.

hello everyone today we are discussing
squares and properties of squares
what is a square when we multiply a
number with itself we say that number
has been squared or the product is
called square of that number for example
3 into 3 is 9 that means square of 3 is
9 the square numbers are called perfect
squares a natural number is called a
perfect square when it is square of some
other natural number
properties of squares a natural number
having two three seven and eight at once
place is never a perfect square for
example number 12 23 4768 are not
perfect squares natural numbers having
zero one four five six or nine at once
place may or may not be a perfect square
for example when we look at numbers 101
21 to 25 289 324 or 256 these are all
perfect squares of 10 11 15 17 18 and 16
respectively but when we look at the
numbers 10 to 21 to 24 235 326 or 389
these have the n digits as zero one four
five six nine but these are not perfect
squares
number ending with odd number of zeros
is never a perfect square for example
take number 40 it is only 10 and it is
not a perfect square take number 1000 it
has three zeros it is not a perfect
square
next square of an odd number is always
odd for example three square is nine
which is an odd number 13 square is 169
again which is an odd number
square of an even number is always an
even number for example 12 square is 144
16 square is 256 these are what even
numbers factors of a square number can
be clothed in pairs of equal numbers for
example 7 29 now 729 factors are free
multiplied six times that means we can
make pairs of three three times so
factors of a square number can always be
grouped together in a pair
square of a number ending with one or 9
ends always with one take for example 11
square it is 121 and Ingrid digit 190
and square is 365 again the number is
ending with digit 1 square of a number
ending with 3 or 7 always ends with 9
for example 13 square is 1 69 and Ingrid
eject 917 square is 289 again ending
footage 89
next we move forward to square of a
number ending with four or six ends with
digit six let's have a look 14 square is
196 16 square is 256 square of a number
ending with digit 5 this one is easy
always ends with 55 square is 25 15
square is 225 square of a number ending
with digit 0 always ends with even
number of zeros for example 10 square is
100 we have two pair of zeros 20 square
is 400 again we have 20
I'll hope you like to listen and enjoy
it see you soon with a mixed listen on
cubes and properties of you thank you
