Answer 1

Question : The perimeter of rectangular garden is 160 m. If it is 10 m wide, find the length of rectangular garden.

Answer :

70 m

Step-by-step explanation :

Let the length of rectangular garden be x.

And, breadth = 10 m

According to the question ;

Perimeter of rectangle = 160 m

⇒ 2 ( l + b ) = 160

⇒ 2 ( x + 10 ) = 160

⇒ x + 10 = 160 / 2

⇒ x + 10 = 80

⇒ x = 80 - 10

⇒ x = 70

Hence, the length is 70 m.
