Question

How much wire will be needed to make a rectangle 7cm long 4cm wide

Answer 1

We first need to find out perimeter
So 2×l+b
2×7+4
2×11
22m
So 22nd of wire is needed

Answer 2

Answer:

Wire needed to make the rectangle= 22 cm

Step-by-step explanation:

Given

Length of the wire (l)= 7 cm,

Width of the wire (w)= 4 cm,

Wire needed to make a rectangle= Perimeter of the rectangle

= 2(l+w)

= 2(7 cm + 4 cm )

= 2 × 11 cm

= 22 cm

Therefore,

Wire needed to make the rectangle= 22 cm
