I hope this helps you




perimeter of square =4x


4x=equilateral triangle perimeter


4x=3.1


x=3/4

Answer:

The length of a side of the square is given by x

The length of a side of the equilateral triangle is given by x=1

Given is : The perimeter of a square is equal to the perimeter of an equilateral triangle.

Perimeter of square is given as 4 x side.

Perimeter of equilateral triangle is given as 3 x side.

So, we will make both equal.

[tex]4x=3x[/tex]

As x = 1 for triangle, the equation becomes:

[tex]4x=3[/tex]

So, [tex]x=3/4[/tex]
