Question

If an equilateral triangle and a square have same perimeter"a". The sum of the length of their side is​

Answer 1

Answer:

7a/12

Step-by-step explanation:

Perimeter of equilateral triangle = a

Side of equilateral triangle = a/3

Perimeter of square = a

Side of square =  a/4

The sum of the length of their side = a/3 + a/4

                                                          = (4a + 3a)/ 3x4

                                                           = 7a/12

Answer:

answer in the explanation

Step-by-step explanation:

Let the sides be:

a

- the side of the square,

b

- the side of the triange.

The perimeters of the figures are equal, which leads to:

4

a

=

3

b

If we divide both sides by

3

a

we get the required ratio:

b

a

=
