By

Using

Length and width

Answer 2

The perimeter of plate is 84.84 m

Step-by-step explanation:

Let the side of square plate be  x

Diagonal of square = $a\sqrt{2}$

Where a is the side of square

So, Diagonal of square plate = $x\sqrt{2}$

We are given that Square shaped wooden plate has a diagonal length of 30cm

So, $x\sqrt{2}=30\\x=\frac{30}{\sqrt{2}}\\x=21.21$

Perimeter of square plate = $4 \times side = 4 \times 21.21 = 84.84 m$

Hence The perimeter of plate is 84.84 m
