length = 36 cm

breadth = 30 cm

perimeter = 2(length + breadth)

=2(36 + 30)

= 2 × 66

= 132 cm

let the radius of the circle be r.

so the circumference of the circle =132 cm

2πr = 132 cm

2 × 22/7 × r = 132 cm

r/7 = 3 cm

r = 21 cm

ANSWER:The length of wire

=Perimeter of rectangle

=2×(36+30)cm

=2×66cm

=132cm.

The circumference of the circle made by the wire will be equal to the perimeter of the rectangle.

2πr=132cm

or r=132×7/2×22cm=21cm.
