Ascale model of a rectangular building lot measures 7 feet by 5 feet. if the actual house will be built using a scale factor of 12, what is the area of the actual building lot? 35 square feet 420 square feet 840 square feet 5,040 square feet

answer: 840

step-by-step explanation:

5040 square feet

Step-by-step explanation:

Data provided in the question

Dimensions of the model:

7 feet by 5 feet

scale factor = 12

now,

the original dimensions of the plot after applying the factor

7 feet × 12 = 84 feet

5 feet × 12 = 60 feet

therefore,

The area = 84 feet × 60 feet = 5040 square feet

hence, the correct option is 5040 square feet

Actual area of the rectangular building = 5040 feet²

Step-by-step explanation:

Length of the rectangular building = 7 feet

Width of the rectangular building = 5 feet

Now, The building is made with a scale factor of 12

So, Actual length of the rectangular building = 84 feet

Actual width of the rectangular building = 60 feet

Now, Actual area of the rectangular building = Length × Width

⇒ Actual area of the rectangular building = 84 × 60

⇒ Actual area of the rectangular building = 5040 feet²

Step-by-step explanation:

Step-by-step explanation:

7feet x 5 feet= 35 feet squared

35x12= 420 square feet

The answer is 5,040

This is because

7 x 12 = 84

5 x 12 = 60

84 x 60 = 5,040
