Question

What is the perimeter of a square when the area is 132

Answer 1

Perimeter= 45.96cm ( 2 d.p) / 46.0cm (1 d.p)

Explanation:

A square has the same sides wherever you place it, and when you want to find the area of a square you use the formula base times height:

`A= bh`

if the A= 132 you can just square root it first:

One side =
`√(132)`
`= 2√(33)`

Leave the surd as it is to get an accurate answer.

Perimeter of a square involves multiplying the one side by 4 so:

`4` ×
`2√(33)` = 45.9565cm

Round it up to (1 d.p) or (2 d.p)

Perimeter= 45.96cm ( 2 d.p)

Perimeter= 46.0cm (1 d.p)

Hope it is right, ask any question if you are unsure! :)
