Question

Find the side length of each of the following squares having area


16cm2

Answer 1

The side length of the each areas are (a) 4 cm (b) 12 cm (c) 6 cm (d) 7 cm (e) 8 cm (f) 2 cm .

Explanation:

Given:

The areas of the squares:

(a) 16 cm² (b) 144 cm² (c) 36 cm² (d) 49 cm² (e) 64 cm² (f) 4 cm².

Now, finding the side length of each squares.

So, putting the formula of area of square for getting the side length(a):

(a) Area = a²

`16 = a^(2)`

Using square root both the sides we get:

`4=a`

Side length = 4 cm.

(b) Area = a²

`144 = a^(2)`

Using square root both the sides we get:

`12=a`

Side length = 12 cm.

(c) Area = a²

`36= a^(2)`

Using square root both the sides we get:

`6=a`

Side length = 6 cm.

(d) Area = a²

`49 = a^(2)`

Using square root both the sides we get:

`7=a`

Side length = 7 cm.

(e) Area = a²

`64 = a^(2)`

Using square root both the sides we get:

`8=a`

Side length = 8 cm.

(f) Area = a²

`4=a^(2)`

Using square root both the sides we get:

`2=a`

Side length = 2 cm.

Therefore, the side length of the each areas are (a) 4 cm (b) 12 cm (c) 6 cm (d) 7 cm (e) 8 cm (f) 2 cm.
