Question

how much wire will be needed to make a rectangle of length 6 cm and breadth 3cm​

Answer 1

The wire needed to make a rectangle of length 6 cm and breadth 3 cm​ is

18 cm in length.

• The wire will form the boundary of the rectangle.

• The boundary will be the perimeter of the rectangle.

• We know that, perimeter of rectangle can be calculated as:

        2(l + b)

        here, l = length

                 b = breadth

• As per question, l = 6cm and b = 3 cm.

• Therefore, Perimeter = 2 (6 + 3) cm

                                            = 2 (9) cm

                                            = 18 cm.

Answer 2

18 Cms of wire is required to make a rectangle of length 6 cms and breadth 3cm​s

Explanation:

• This question indirectly asks us, how much area is needed to cover the given rectangle with the wire. This is a simple application of the Area formula of the rectangle.

• We know that for any rectangle of Length (L) and Breadth (B) is given by $Area = Length X Breadth$  
• Here substituting Length and Breath in the above equation, we get $Area of the wire = 6 cms X 3 cms = 18 cms$
