Answer:
Width is 8 ft
Step-by-step explanation:
The perimeter of the rectangle is given by the formula
P=2(l+b) ------(A)
Where we are given with the values as
P=40 ft
l=12 ft
Putting these values in (A)
40=2(12+b)
Dividing both sides by 2 we get
20=12+b
Subtracting 12 from both sides we get
8=b
Hence the width of the rug us 8 ft
The width of the rectangular rug is 8 feet and this can be determined by using the formula of the perimeter of a rectangle.
Given :
The formula of the perimeter of a rectangle is:
[tex]\rm P = 2\times (L + W)[/tex]
where L is the length of the rectangle and B is the width of the rectangle.
Now, put the values of perimeter P and length L in the above equation.
[tex]\rm 40 = 2\times (12+ W)[/tex]
Further, simplify the above expression.
[tex]\rm 20 = 12 +W[/tex]
W = 8 feet
The width of the rectangular rug is 8 feet.
