Answer:
The width of the rectangular room =x= 8
Step-by-step explanation:
Given: A rectangular room is twice as long as it is wide, and its perimeter is 48 meters.
To find: The width of the room.
Solution: Let the width of the rectangular room= x meters, then the length of the rectangular room will be = 2x.
Now, Perimeter of rectangular room=2(l+b)
⇒48=2(2x+x)
⇒24=3x
⇒x=8 meters
Then, the width of the rectangular room =x= 8 meters and the breadth of the rectangular room=2x=2(8)=16 meters.
Answer:
8m
Step-by-step explanation:
Let the length of thw room be L and the width be W. If the rectangular room is twice as long as it is wide then L = 2W.
The formula for perimeter of a triangle will be addition of all the sides of the rectangle.
Since we have two sides and 2 width in a rectangle, the perimeter;
P = L+L+W+W
P = 2L+2W
Given perimeter = 48m
48 = 2L+2W
Substituting L = 2W into the equation gives;
48 = 2(2W)+2W
48 = 4W+2W
48 = 6W
W = 48/6
W = 8m
Therefore the width of the rectangular room will be 8m
