Question :-

The perimeter of a rectangular sheet is 100 cm. If the length is 35 cm, find its breadth. Also find the area.

given :-

• Length = 35cm
• Breadth = ?
• Perimeter = 100cm

To find :-

• Breadth of rectangle
• Area of rectangle

Solution :-

Perimeter

⇒ 2(l + b)

⇒100 = 2(35 + b)

⇒ $\dfrac{100}{2}$=35+b

⇒ 50 = 35 + b

⇒ b = 50 – 35

= 15 cm

∴ Breadth = 15 cm

_________

Area

= l × b

= 35 cm × 15 cm

= 525 ${cm}^{2}$
