how to solve this

please tell step by step

Answer 1

Answer:

31cm

Step-by-step explanation:

Perimeter of the rectangle will be equal to the perimeter of the square formed, as the wire is same, therefore,

perimeter of rectangle = 2 × ( L + B )

⇒ 2 × ( 40 + 22 )

⇒ 2 × 62

⇒ 124cm

Perimeter of square = 4 × side

⇒ 124 = 4 × side

⇒ $\frac{124}{4}$ = side

⇒ 31cm = side

Answer 2

Answer:

A wire is in the shape of a rectangle whose length is 40 cm and breadth is 22 cm. If it is straightened and bent into the shape of a square. The side of the square is 31 cm.

Step-by-step explanation:

Length of the rectangle = 40 cm

Breadth of the rectangle = 22 cm

Since the same length of wire is used to form a rectangle and square, we can say that, the perimeter of square = perimeter of the rectangle

4 × Side = 2 (Length + Breadth)

4 × Side = 2 (40 + 22)

4 × Side = 2 × 62

4 × Side = 124

Side = 124/4

Side of square = 31 cm

Hence the side of the square is 31 cm.
