Answer 1

The area of the room = (40 x 24) - (20 x 12)

Area = 960 - 240 = 720 square feet

Divide square feet by width of a strip:

720 / 12 = 60 linear feet.

The answer is D.

Answer 2

Answer : The correct option is, (D) 60

Step-by-step explanation :

First we have to calculate the area of room.

Area of room = Area of big rectangle + Area of small rectangle

Area of rectangle = Length × Width

Area of room = (40 × 12) + (20 × 12)

Area of room = 720 square feet

Now we have to calculate the number of linear feet will he need to buy.

Number of linear feet = $\frac{\text{Area of room}}{\text{Width of carpet strips}}$

Number of linear feet = $\frac{720}{12}=60$

Thus, the number of linear feet will he need to buy is, 60
