Question

find the length of the diagonal of a square if it area is 30. 25 CM square give the answer in term of root over 2 plzz answer plzz

Answer 1

Area=Side ×Side

===
===

30.25cm²=S²
√30.25=S
5.5=S

As we all side of square is equal in length

So, we can use Pythagoras theorem to find the diagonal

Let d be diagonal

d²=S²+S²
d²=5.5²+5.5²
d²=30.25+30.25
d²=60.50
d=√60.50cm
or
d=7.7cm

Answer 2

Answer:

⇒ 5.5√2

Step-by-step explanation:

Given, Area = 30.25 cm^2.

⇒ Area = s^2

⇒ 30.25 = s^2

⇒ √30.25 = s

⇒ 5.5 = s.

We know that Diagonal = (Side length) * √2.

Length of the diagonal = 5.5√2.

Therefore, the length of the diagonal = 5.5√2.

Hope it helps!
