Question

22.
The length of a room is two and half times its width. If the perimeter of the floor of the room is 70
find the length and width of the room.​

Answer 1

Answer:

Length = 5/2 * b = 25

Breadth = 10

Step-by-step explanation:

Let width be b and length be 5/2b

Therefore perimeter =

2*(b+5/2b)= 70

7b/2 = 35

b = 35/7 *2

b = 10
