Question

A length of a rectangle is 100 cm and its breadth is 75 cm . The ratio of length of the rod to its perimeter

• A. The ratio of length of snake to crocodile is 5:1
• B. 1 : 4
• C. 4 : 1
• D. 3 :1

Answer 1

The correct option is A

The ratio of length of snake to crocodile is 5:1

The length of the rectangle = 100 cm

The breadth of the rectangle = 50 cm

Hence Perimeter = 2( l + b)

= 2( 100 + 50)

= 2(150) = 300 cm

Hence ratio of the length of the rod to Perimeter of the rectangle = $\frac{Lengthoftherod}{Perimeteroftherectangle}$

= $\frac{100}{300}$

=$\frac{1}{3}$

Ratio of Length to the perimeter of the rectangle = 1 : 3
