Mariko has an 80 inches = 1 inch scale- drawing of the floor of her house. On the floor plan, the dimension of her rectangular living room are 1 7/8 inches by 2 1/2 inches. What is the area of her real living room in square feet?

1 inch is actually 80 inch so:

1 7/8 x 80 is true length of side 1 and
2 1/2 x 80 is true length of side 2 of room

the area is side 1 x side 2 in sq inches
then change square inches to square feet for your final answer

Im from the future obey me mortals

Idk man but the answer is the answer

To find the area of Mariko's real living room, we need to first convert the dimensions from inches to feet and then calculate the area in square feet.

Step 1: Convert the dimensions from inches to feet
Since there are 12 inches in a foot, we can divide the given dimensions in inches by 12 to convert them to feet:

Length: 1 7/8 inches = (1 + 7/8) inches = (15/8) inches = (15/8) / 12 feet
Width: 2 1/2 inches = (2 + 1/2) inches = (5/2) inches = (5/2) / 12 feet

Step 2: Calculate the area in square feet
To find the area of a rectangle, we multiply the length by the width:

Area = Length × Width

Now, let's compute the area:

Area = ((15/8) / 12) feet × ((5/2) / 12) feet

To simplify the calculation, let's first multiply the numerators and denominators separately:

Area = (15 × 5) / (8 × 2) × (1 / 12 × 12)

Now, let's perform the multiplication and division:

Area = (75 / 16) × (1 / 144)

To multiply fractions, we multiply their numerators and denominators:

Area = (75 × 1) / (16 × 144)

Area = 75 / 2304

Therefore, the area of Mariko's real living room is 75/2304 square feet.

Note: The area is in fractional form, so you can leave it as is or simplify it further.
