Question

How many we needed wire from making rectangle 7 cm long and 4 centimetre wide

Answer 1

Answer:

Step-by-step explanation:

LENGTH ,L = 7 CM

BREADTH ,B = 4 CM.

WIRE NEEDED = 2(L+B)

                         = 2(7+4)

                         = 2(11)

                         = 22 CM.

THEREFORE THE LENGTH OF WIRE NEEDED TO MAKE THE RECTANGLE IS 22 CM.

HOPE THIS HELPS.

Answer 2

The length of wire required is the perimeter of the rectangle which is equal to 2 times the product of length and breadth

l= 7cm

b= 4cm

Perimeter= 2(l+b)=2(7+4)=2(11)=22

Therefore the length of wire required is 22cm
