Lucinda wants to build a square sandbox, but she has no way of measuring angles. explain how she can make sure that the sandbox is square by only measuring length.
a. arrange four equal-length sides so the diagonals bisect each other.
b. arrange four equal-length sides so the diagonals are equal lengths also.
c. make each diagonal the same length as four equal-length sides.
d. not possible; lucinda has to be able to measure a right angle.

The diagonals of the square have the same length (property of a square).
Lucinda must arrange four equal-length sides so the diagonals are equal lengths also.

Step-by-step explanation:

Given

Area of a circle (A) = 641 ft²

Circumference (C) = ?

We know

πr² = 641

r² = 641 / 3.142

r² = 204

r = 14.28 ft

Now

Circumference

= 2πr

= 2 * 3.14 * 14.28

= 89.68 ft

Hope it will help :)
