Answer:
Given :
Wire is in shape of square of side 10cm
The same wire is rebent into rectangle of length 12xm
To find :
Breadth of new rectangle formed
Procedure :
Firstly find perimeter of square, this will give us length of wire
The perimeter of rectangle will be equal to perimeter of square , as length of wire is same
Formula used :
Perimeter of square = 4×side
Perimeter of rectangle = 2(length + breadth)
Solution :
Perimeter of square = 4×10 = 40cm
as perimeter of square = perimeter of rectangle
therefore, Perimeter of rectangle = 40cm
Perimeter of rectangle = 2×(length+ breadth)
=> 40 = 2×(12+breadth)
=> (40/2) = (12+ breadth)
=> 20 = 12 + breadth
=> breadth = 20-12
=> breadth = 8cm
