Question

The perimeer of a rectangular sheet is 40 feet. If the length of the sheet is three times the breadth, find its dimensions.​

Answer 1

length = 15feet

breadth = 5feet

Answer 2

AnswEr :

• Perimeter of Rectangular Sheet is 40feet.
• Length of Sheet is three times the Breadth.
• Find the Dimensions.

⋆ Let the Breadth be n feet

⋆ Length = Three Times of Breadth

» Length = 3 × n feet

» Length = 3n feet

• Now According to Question ;

⇒ Perimeter of Rectangle = 2 × (Length + Breadth)

• Plugging the Values

⇒ 40 = 2 × ( 3n + n )

⇒ 40 = 2 × 4n

⇒ 40 = 8n

• Dividing Both term by 8

⇒ n = 5

◑ Length = 3n = (3 × 5) = 15 feet

◑ Breadth = n = 5 feet

჻ Dimensions of Rectangular Sheet is 15 feet long and 5 feet wide.
