Answer» Radius of circular wire= 10.5 cmCircumference of circular wire = 2×22/7×10.5=>66 cmAs the rectangle is made up of same piece of wire then circumference of circle is equal to perimeter of rectangle Perimeter of rectangle =2(l+b)=> 66=2(20+b)=> 66/2=20+b=> 33= 20+b=> 33- 20= b=> 13 = bTherefore breadth of the given rectangle is 13 cm. |
