Given:
Dimensions: 8ft by 10ft
Determine the perimeter of the bedroom floor
Perimeter of rectangle:
P = 2(l + w)
Explanation:
If 1 ft is exposed on all four sides, then this means that we need to add 1 ft on to the dimension of the rug in order to determine the dimensions of the bedroom floor.
Dimension of bedroom floor = 9ft by 11 ft
Solution:
Since we now know the dimensions of the bedroom floor, we simply substitute the given values to the formula for perimeter.
P = 2(l + w)
P = 2(8ft + 10ft)
P = 2 (18ft)
P = 36ft
Final answer:
The perimeter of the bedroom is 36ft.
