Question

Q 1. A piece of string is 48 cm long.
What will be the length of the side if the
string is
used to form
(a) a square ?
(b) an equilateral triangle ?
​

Answer 1

HERE'S YOUR ANSWER BUD

(a) as we all know square have 4 equal side,

    so therefore each side of square is this long=48x1/4

                                                                                 =12cm

(b)equilateral have 3 equal side,so therefore

each side of equilateral triangle=48x1/3

                                                       =16cm

Answer 2

Answer:

(a) The length of each side if the string is used to form a square is 12 cm .

(b) The length of each side if the string is used to form an equilateral triangle is 16 cm .

Step-by-step explanation:

Given: A piece of string is 48 cm long .

To find : The length of each side if the string is used to form

(a) A square

(b) An equilateral triangle

Solution :

(a) If the string is used to form a square ,

The perimeter of the square P = 4a

where , P = 48 cm is the perimeter.

a is the length of the side .

Therefore , 48 = 4a

a = 48 ÷ 4

a = 12 cm .

The length of each side if the string is used to form a square is 12 cm .

(b) If the string is used to form an equilateral triangle ,

The perimeter of an equilateral triangle is P = 3a

where , P = 48 cm is the perimeter of the triangle.

a is the length of the each side of the triangle .

Therefor , 48 = 3a

a = 48 ÷ 3

a = 16 cm .

The length of the each side if the string is used to form an equilateral triangle is 16 cm .
