1 point
8 cm
None of these
10 cm
25/3 cm​

Answer 1

Perimeter of the square = 4× side

=> 4×10

= 40 cm

As the wire is bent into rectangle having length 12 cm

Since Perimeter of square = Perimeter of rectangle

40= 2(l+b)

20= 12+b

b= 8 cm

Area of square = 10²= 100 cm²

Area of rectangle= l×b= 12×8= 96cm²

Lost in area = 100-96= 4cm²
