Step by step explanation:-

Given:-

• Rectangle and square have the same perimeter 100m.

To find:-

• Side of square.
• Length of rectangle.
• Breadth of rectangle.

$\huge \tt \: Solution$

Area of square = 4a

In which a is side of square.

⇒ 100 = 4a

⇒100/4 = a

⇒25 = a

Side of square 25 cm.

Given that,

Breadth of rectangle = a - 2 ( a id side of square).

⇒25 - 2 cm

⇒23 cm.

Breadth of rectangle = 23 cm.

Perimeter of rectangle = 2 (l + b)

⇒100 = 2 ( 23 + l )

⇒100 = 46 + 2l

⇒100 - 46 = 2l

⇒54 = 2l

⇒54/2 = l

⇒27 = l

Length of rectangle = 27 cm.
