# 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. 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 cm
