Question

The measure of two adjacent sides of a
rectangle is in the ratio 11:10 If the perimeter,
of the rectangle is 84 cm, then find its length
and breadth.​

Answer 1

Answer:

the length,   l =  22m

the breadth,b=  20m

Step-by-step explanation:

Given that the ration of 2 adjacent sides of a rectangle = 11:10

let x be the proportion

=> 11x and 10x are the length & breadth of the rectangle

=> perimeter , p = 2(l+b) units

=> 84 = 2 (11x+10x)

=> 84 = 2(21x)

=> 21x = 84/2 = 42

=> x = 42/21

=> x = 2

so, the length, l = 11x = 11*2 = 22m

and the breadth,b=10x = 10*2 = 20m
