Question

A metal wire is in the shape of a square whose side is 84m . it is then rebent into a rectangle of width 21 m .find it's length

Answer 1

Perimeter of square = 4×side

Perimeter of square =4×84

Perimeter of square =336m


__________

Perimeter of square = perimeter of rectangle


336= perimeter of rectangle

336=2(lenght+ breadth) of rectangle


336/2= lenght +21

168=lenght +21

168-21 = lenght

147 m = lenght



I hope this will help you

Answer 2

Hiii friend,

Side of square wire = 84 M

Perimeter of square wire = Perimeter of rectangle wire.

4 × Side = 2(Length+ Breadth)

4 × 84 = 2(Length + 21)

336 = 2Length + 42

2 Length = 336-42

2 × Length = 294

Length = 294/2

Length = 147

Hence,

The Length of rectangle wire = 147 M

HOPE IT WILL HELP YOU.... :-)
