Question

A wire is in the shape of a square of side 20 cm. If the wire is bent into a rectangle
of length 24 cm, find its breadth
​

Answer 1

Answer:

Length of square L=20cm

Length of rectangle l=24cm

Breadth of rectangle b=?

Now, perimeter of square=perimeter of rectangle

⇒4(L)=2(l+b)

⇒4(20)=2(24+b)

⇒

2

80

=24+b

⇒40=24+b

⇒16=b.

Breadth of rectangle b=16 cm

Answer 2

Side of square = 20 cm

Perimeter of square = 4 x 20

                                     = 80 cm

Length of rectangle = 24 cm  

Perimeter of a rectangle = 2 (l+b)

b = 40 - 24 = 16 m

Hence, the breadth of the rectangle is 16 m.
