Question

Find the ratio of perimeter to area of square with side 12 cm.​

Answer 1

Step-by-step explanation:

Perimeter of square = 4 * side

= 4*12 sq. cm

= 48 sq. cm

Area of square = (one side) ^2

= (12)^2 sq. cm

= 144 sq. cm

The ratio is

Perimeter : Area

= 48 : 144

= 1 : 3

Answer 2

• Ratio is 1:3 .

Step-by-step explanation:

To find:-

• Ratio of perimeter and area of square.

Solution :

Given that,

Side of square is 12 cm.

Perimeter of square = 4×side

$\longrightarrow$ 4 × 12

$\longrightarrow$ 48

Perimeter of square is 48 cm.

Area of square = Side × Side

$\longrightarrow$ 12 × 12

$\longrightarrow$ 144

Area of square is 144 cm².

Ratio = Perimeter of square/Area of square

$\longrightarrow \cfrac{48}{144}$

$\longrightarrow \cfrac{1}{3}$

Therefore,

Ratio is 1:3 .
