Answer 2

Solution :-

Given ,

• Perimeter of rectangle = 720 cm
• Breadth = 150 cm

We need to find ,

• Length of rectangle = ?

As we know that ,

• Perimeter of rectangle = 2( l + b )

Substituting known values we have ,

⇒ Perimeter = 2 ( l + b )

⇒ 720 cm = 2 ( l + 150 )

⇒ 720 = 2l + 300

⇒ 720 - 300 = 2l

⇒ 420 = 2 l

⇒ l = 420 ÷ 2

⇒ Length of rectangle = 210 cm

Hence , length of Rectangle = 210 cm
