Question

3. The length and breadth of a rectangle are 25 cm
and 15 cm. Find the ratio of
(a) its length to its breadth.
(b) its length to its perimeter
(c) its breadth to its perimeter.
​

Answer 1

Answer:

a)5/3 , b)5/16 , c)3/16

Step-by-step explanation:

perimeter formula (rectangle)  =  2(length+breadth)

Answer 2

Answer:

A) 5:3

B) 5:16

C) 3:16

Step-by-step explanation:

A) Length= 25 cm and breadth= 15cm

Dividing both, 25/15= 5/3

Hence,

Ratio of length is to its breadth is 5:3.

B) Length= 25cm and perimeter=2(25+15)=2×40

This implies that,

Length= 25cm and perimeter= 80 cm

Dividing both, 25/80= 5/16

Hence,

Ratio of length to its perimeter is 5:16.

C) Breadth= 15cm and perimeter= 80cm

Dividing both, 15/80= 3/16

Hence,

Ratio of breadth to its perimeter is 3:16.

Hope it helps:)
