# Let us see the card below, find perimeter and let us write by calculating what will be the length of one side of equilateral triangle with same perimeter.

Answer :

**Note:** Perimeter of equilateral triangle with side ‘a’ is

(i)Perimeter of rectangle

Where a = length and b = breadth of rectangle respectively

cm

cm

Now, the perimeter of Equilateral triangle cm

cm

cm

(ii)Perimeter of square

Where a = side of square

cm

cm

Now, the perimeter of equilateral triangle = 36 cm

cm

cm

(iii)Perimeter of quadrilateral = The distance covered to go one round along perimeter

cm

cm

Now, the perimeter of equilateral triangle = 39 cm

cm

cm

(iv)Perimeter of parallelogram = 2 (a + b)

Where a = length and b = breadth

cm

cm

Now, the perimeter of equilateral triangle = 66 cm

cm

cm

(v)Perimeter of triangle = (a + b + c)

Where a, b and c are sides of triangle respectively

cm

cm

Now, the perimeter of equilateral triangle = 30 cm

cm

cm

(vi)Perimeter of triangle = (2a + b)

Where a and b are sides of isosceles triangle

cm

cm

cm

Now, the perimeter of equilateral triangle = 45 cm

cm
