Question

Area of a square plot 6561 m2. Find the length of the dragonal.​

Answer 1

Explanation:

Area of a square using diagonals = Diagonal²:2

so Diagonal = √(Area *2)

√(6561*2) =

√13122 =

114.55

-----------------------------------------------------------------

114.55² = 6561

the answer is good

Answer 2

Do you mean diagonal? If so, I think the answer is 114.55 metres.

Explanation:

It might be wrong, but here's what I think.

We need to find out
`√(6561)` first.

`√(6561) = 81`

Use Pythagoras' theorem.

Divide the square into two along the diagonal.

You want to find out the hypotenuse of one of the triangles. Two of the sides are known, and both of these are 81 m.

`a^(2) +b^(2) = c^(2)`

Substitute 81 into a and b:

`81^(2) + 81^(2) = c^(2)`

Find out what
`81^(2)` is.

`6561 + 6561 = c^(2)`

Add.

`13122 = c^(2)`

Figure out the value of c.

`√(13122) = c\\c = 114.5512986`

Round to 2 decimal places.

Answer: 114.55
