Question

the breadth of a rectangular garden is 2/5 of its length . if its perimeter is 40m , find its dimensions .​

Answer 1

Answer:

8 m

Step-by-step explanation:

let length of the rectangular garden (l) = x

and breadth =2/5 of its length

=2/5x

=> 2(x+2/5x)=40m

=> 2(5x/5) =40 m

=> 5x/5 =40/2

=> 5x/5 =20 m

=> 5x=100 m

=> x=100/5

=> x=20

Therefore, length (l) = 20 m

and breadth (b) =2/5×20

= 8 m
