Question

Qn.3. A length of wool is placed in such a way that it forms a rectangle, the length of which is 9cm
and its breadth is 4cm. If the same length of wool is placed in such a way that it forms a
square, what will be the length of the side of that square?​

Answer 1

Answer:

the length of the side of that square is 6.5 cm

Answer 2

Since the shape of the rectangle forms a square,therefore,

Then,l=9cm,b=4 cm

Perimeter of the square=Perimeter of the rectangle

4×length of a side=2×(l+b)

4×length of a side=2×(9+4)

4×length of a side=2×13

4×length of a side=26cm

Ans=26cm
