) 19m
) 91m
81m​

Answer 1

Correct Question :

Find the length of the side of a square field and the area of the field is 8281 m².

a) 19 m.

b) 91 m.

c) 81 m.

⠀⠀⠀⠀

Answer :

Correct option is (b) 91 m.

• The length of the side of a square field = 91 m.

⠀⠀⠀⠀

Given :

• The area of a square field = 8281 m².

⠀⠀⠀⠀

To Find :

• The length of the side of a square field.

⠀⠀⠀⠀

Solution :

Given,

Area of the field = 8281 m²

We know that,

Area of square = Side²

That means,

$\implies {side}^{2} = 8281 \: {m}^{2} \\ \\ \implies side = \sqrt{8281 \: {m}^{2} } \\ \\ \implies side = 91 \: m$

Hence,

The length of the side of a square field is 91 m.

So, the option (b) 91 m is correct.

⠀⠀⠀⠀

Verification :

We have,

Area of the field = 8281 m².

Side of the field = 91 m.

We know that,

Area of a square = Side²

$\implies {side}^{2} =8281 \: {m}^{2} \\ \\ \implies {(91 \: m)}^{2} = 8281 \: {m}^{2} \\ \\ \implies91 \: m \times 91 \: m = 8281 \: {m}^{2} \\ \\ \implies8281 \: {m}^{2} = 8281 \: {m}^{2}$

Hence Verified !

Answer 2

Question :-

Find the length of the side of a square field and the area of the field is 8281 m².

a) 19 m.

b) 91 m.

c) 81 m.

⠀⠀⠀⠀

Answer :-

• The side of square field is 91 m.

Given :-

• Area of the field = 8281 m².

To find :-

• Side of square.

Solution :-

$\boxed{ \large{ area \: of \: square = {side}^{2} }}$

$\implies \: 8281 = {side}^{2} \\ \implies \: \sqrt{8281} = \cancel{ \sqrt{ {side}^{ \cancel{2} } }}</p><p></p><p></p><p> \\ \implies \: \sqrt{8281 } = side \\ \implies \: side \: = 91m$

Hence,

The side of square field is 91 m.
