Answer 1

Step-by-step explanation:

i) Ans = 12.52cm

METHOD:-

EQUILATERAL TRIANGLE = 3 SIDES

PERIMETER = SUM OF ALL SIDES

SO , ONE SIDE = 37.56/3 =12.52CM = LENGTH OF ONE SIDE.

ii) Ans = 2.54m

METHOD:-

TOTAL LENGTH OF WIRE = 53.34M

IT IS DIVIDED INTO 21 PIECES

SO, LENGTH OF ONE PIECE = 53.34/21 = 2.54 M
