Question

a wire is in shape of square of side 12cm if the wire is rebend into a rectangle of length 14cm find its breadth​

Answer 1

perimeter of square= perimeter of rectangle

4×side =2(l+b)

4×12=2(14+b)

48=2(14+b)

48/2=14+b

24 =14+b

24-14 = b

10 = breadth

please follow me

Answer 2

Answer:

10 cm

Step-by-step explanation:

Let the bredth be x

Then ATQ => 4*12 = 2(14 + x)

                 => 48 = 28 + 2x

                 =>48 - 28 = 2x

                 =>2x=20

                 =>x = 20/2

                 =>x = 10

Therefore Bredth is 10 cm
