1.	The perimeter.of a rectangular sheet is 100 cm. If the length is 35 cm, find its breadhAlso find the area.
Answer» Given that Perimeter of a rectangular sheet = 100cm Length = 35cm Solution Let the breadth of a rectangular sheet be x cm.Then, according to question, Perimeter of a rectangular sheet = 2(l+b) => 100 = 2(35+b) => 100/2 = 35+b => 50 = 35+b => -b = 35-50 => -b = -15 => b = 15cm Area of a rectangular sheet = l×b = (35×15)cm^2 = 525cm^2

Answer»

Given that

Perimeter of a rectangular sheet = 100cm

Length = 35cm

Solution

Let the breadth of a rectangular sheet be x cm.Then,

according to question,

Perimeter of a rectangular sheet = 2(l+b)

=> 100 = 2(35+b)

=> 100/2 = 35+b

=> 50 = 35+b

=> -b = 35-50

=> -b = -15

=> b = 15cm

Area of a rectangular sheet = l×b

= (35×15)cm^2

= 525cm^2
