What is the total square footage of a first floor measuring 10x15 feet for the kitchen, 20x25 feet for the living/dining area, and 10x10 feet for the office and bedroom?

To find the total square footage, we need to calculate the area of each individual room and then sum those areas.

1. For the kitchen measuring 10 feet by 15 feet:

• Area = Length × Width = 10 ft × 15 ft = 150 square feet.

2. For the living/dining area measuring 20 feet by 25 feet:

• Area = Length × Width = 20 ft × 25 ft = 500 square feet.

3. For the office and bedroom, each measuring 10 feet by 10 feet:

• Area for each room = Length × Width = 10 ft × 10 ft = 100 square feet.

• Since there are two of these rooms, the total area for both is 100 sq ft + 100 sq ft = 200 square feet.

Now, we sum the areas of all the rooms:

• Kitchen: 150 square feet

• Living/Dining Area: 500 square feet

• Office: 100 square feet

• Bedroom: 100 square feet

Adding these together gives us:

150 + 500 + 200 = 850 square feet.

Thus, the correct total square footage of the first floor is 850 square feet
