Answer: The required area of the floor is 133.875 sq. ft.
Step-by-step explanation: We are given to find the area of a floor that measures 12.75 ft. by 10.5 ft.
We know that
a floor is of rectangular shape and the area of a rectangle is the product of its dimensions.
For the given floor, we have
length, l = 12.75 ft and width, w = 10.5 ft.
Therefore, the area of the follow is given by
Thus, the required area of the floor is 133.875 sq. ft.

Answer:
b. 58%
Step-by-step explanation:
Calculate the area of the entire rectangle using the formula A = lw.
The lowercase "L" is for length.
"w" is for width.
The lighter square is 10 units long by 5 inches wide.
A = lw
A = (10 in)(5 in) Multiply
A = 50 in²
Calculate the area for the shaded rectangle, 7 inches by 3 inches.
A = lw
A = (7 in)(3 in) Multiply
A = 21 in²
Calculate the area for the non-shaded region by subtracting the shaded area from the total area.
50 in² - 21 in² = 29 in²
The chance that a point in the large rectangle will NOT be in the shaded region is 29/50.
Convert this fraction to decimal form by using a calculator. Divide the top number by the bottom number.
29/50 = 0.58
0.58 is in decimal form. To convert it to a percentage, multiply the number by 100.
0.58 = 58%
Therefore the probability that a point chosen inside the large rectangle is not in the shaded region is 58%.
