Question

3. Find the area of a square of side (1) 10 m (11) 21 cm (iii) 0.5 m (iv) 4 1/3 m
​

Answer 1

Answer:

Step-by-step explanation:

→ Area of a square

Area of a square is characterized as the number of square units required to fill a square.

• In common, the area is characterized as the locale possessed interior the boundary of a level protest or figure.

• The measurement is worn out square units with the standard unit being square meters (m2).

→ Area of a Square Formula

• Area of a Square = Side ×  Side

• The area of square = Side²  square units

→ EXAMPLE

In a square the length is equal to breadth.

So,  area of a square = side × side

The number of 1 cm squares encased = 4

Area = 4 sq cm

4 = 2 × 2

Answer 2

Square:

• It is a quadrilateral whose all four sides are equal in length.
• All the interior angles of the squares are 90° each.
• The two diagonals of the square are equal and bisect each other.

Now,

• The formula to find the perimeter if a square

= 4 * side units

• The formula to find the diagonal of a square is

= (side) √2 units

• The formula to find the area of a square is

= (side)² units sq.

Now,

• FINDING THE AREA OF THE SQUARE-

(i) 10 m

Area = (side)²

Area = (10)²

Area = 100 cm sq.

(ii) 21 cm

Area = (side)²

Area = (21)²

Area = 441 m sq.

(iii) 0.5 m

Area = (side)²

Area = (0.5)²

Area = 0.25 m sq.

(iv) 4 1/3 m = 13/3 m

Area = (side)²

Area = (13/3)²

Area = 169/9 m sq.
