Question

10. Find the area of square of side 4 cm. If the side of square is doubled, find the area of square​

Answer 1

Answer:

Please see the STEP-BY-STEP EXPLANATION

Step-by-step explanation:

Let the square with side 4cm be SQUARE 1

And...

Let the square whose side is doubled be SQUARE 2

Area of SQUARE 1 = Side × side

= 4cm × 4cm

= 16cm. sq.

Side of SQUARE 2 = 4cm × 2 (As it is doubled)

= 8cm

Area of SQUARE 2 = Side × side

= 8cm × 8 cm

= 64cm. sq.

I HOPE THAT THIS WILL HELP YOU....

Answer 2

Given

Side of square 4cm

To Find

Area of square ,Area of square when side gets doubled.

$\sf\huge\bold{\underline{\underline{{Solution}}}}$

Step by step explanation

1. First we have to apply area of square formula then with the use of side we will find the area of square.

Area of square=(side)²

Area of square=(4)²

Area of square=16cm²

When its side gets doubled e.g, 4×2=8cm

Now,new side 8 cm

Area of square=(side)²

Area of square=(8)²

Area of square when side gets doubled=64cm²

Extra information=>

1. square is a type of quadrilateral which have 4 side and 4 vertices.
2. All sides of square is equal or of same length.
3. Sum of Interior angles is 90°
4. Two diagonals are in square and both are equal to each other.
5. length of the side is smaller than the length of its diagonals.

Perimeter of square=4a (a=side)

Area is Space or region which is covered by a solid object/figure it is said to be area of that object.

Area depends upon the dimensions of the figure.If dimensions is larger then larger will be the area of that object/figure and vice -versa.
