Question

Determine the missing side of the square.

Answer 1

Length of the side W = 9cm

Explanation:

A square has all sides equal. So since one side is 9cm, the rest will be 9cm as well. The side marked as 'W' is 9cm.

You can find this in another way (if the length of the sides aren't given) :-

The area is 81
`cm^(2)`

`side^(2)` gives the area

Let's take the side as x.

So,

`x^(2)` = Area

`x^(2)` = 81
`cm^(2)`

x =
`√(81)`

x = 9cm.

So, each side of the square would be 9cm!

Answer 2

The missing side is 9cm.

How I got my answer:

1. Squares have equal sides.

2. The area is 81cm^2, so we have to divide 81 by 9.

81 : 9 = 9cm.
