Answer 1

Cost per answer :- 5 thanx

Now there can be two situations as your question is wrong :-

Either the Question is :-

Find the perimeter of the Rectangle whose width is 3cm and length is 4cm .

Solution :-

Breadth = 3cm

Length = 4cm

Perimeter = 2 × ( L + B)

= 2 × ( 4 + 3 )

= 2 × 7

= 14 cm

Or the question is :-

The dimensions of a cuboid are 3cm , 4cm , 5cm respectively . Find its perimeter.

Solution :-

Breadth = 3cm

Length = 4cm

Height = 5cm

Perimeter = 4 (Length + breadth + height )

= 4 × ( 4 + 3 + 5 )

= 4 × 12

= 48 cm

Hope it helps........
