Question

A wire is bent in the shape of a square of side 20 cm. If the wire is rebent into a rectangle of length 27 cm then find it's breadth ???....plz ansss​

Answer 1

Answer:

breath= 13cm

Step-by-step explanation:

If the wire is bent in the shape of square then the length of the wire is perimeter of the square.

perimeter of the square=4x side

= 4x20

=80çm

the wire is rebent into rectangle.

perimeter of rectangle= 2( length+ breath)

=2x27+2xb

80= 54+ 2b

26= 2b

b= 13cm

Answer 2

Answer:

Length of square L=20cm

Length of rectangle l=27cm

Breadth of rectangle b=? (to be calculated)

,

Now, perimeter of square=perimeter of rectangle

⇒4(L)=2(l+b)

⇒4(20)=2(27+b)

⇒ 80 = 2(27 + b)

⇒80/2 =27+b

⇒40 = 27 + b

⇒ 40 - 27 = b

⇒ 13 = b

or

⇒ b = 13cm

Breadth of rectangle b=16 cm
