Question

A square carrom board has a perimeter of 320 cm.How much is its area?

Answer 1

Perimeter of a square board = 320 cm
Each side = 320/4 = 80 cm
So, area = side x side
= 80cm x 80cm
= 6400 cm square
HOPE it helps...!!!

Answer 2

Answer:

$Area \: of \: the \: carrom\: board (A) = 6400\: cm^{2}$

Step-by-step explanation:

Let length of a edge of the carrom board = a cm

perimeter of a square (P)=320 cm

( given )

=> 4a = 320 cm

$\implies a = \frac{320}{4}$

$\implies a = 80 \:cm$

$Area \: of \: the \: board \\A= a^{2}\\= \left(80\: cm\right)^{2}\\=6400 \: cm^{2}$

Therefore,

$Area \: of \: the \: carrom\: board (A) = 6400\: cm^{2}$
