Question

ABCD is a square. AB = 4cm. what is the perimeter of the square? What is the ratio between length of side and perimeter ?​

Answer 1

Answer:

1:4

Step-by-step explanation:

Perimeter of the square = 4 x side

In square all sides are equal

If AB = 4cm then BC , CD , AD will be 4cm

Perimeter = 4 x 4 = 16cm

Hope it helps u !!

Answer 2

Given:

Square ABCD with side AB = 4 cm

To find:

• The perimeter of the square ABCD.

• To calculate the ratio between the side of the square and the perimeter of the square ABCD.

Solution:

A square is a polygon whose all four sides are of the same length, and all the angles form right angles.

Therefore,

In Square ABCD, the four sides are equal in length.

To calculate the perimeter of the square,

The formula is,

Perimeter = 4 × a

a = the length of the side of the square.

One side of the square ABCD = AB = 4 cm

Perimeter = (4 × 4) cm

= 16 cm

The ratio between the length of the side and the perimeter of the square ABCD is,

= length of the side: Perimeter of square

= 4 : 16

The ratio is,

= 4/16

= 1/4

The perimeter of the square ABCD is 16 cm.

The ratio between the length of the side and the perimeter of the square ABCD is 1: 4.
