Question

select the correct answer. julia has 2 identical rooms in her house. if each room measures 8 feet on one side and 12 feet on another, what is the total area of the rooms? a. 96 square feet b. 156 square feet c. 192 square feet

Explanation:

Step1: Calculate area of one room

The area of a rectangle is $A = l\times w$. Here, $l = 12$ feet and $w = 8$ feet. So, $A_1=12\times8 = 96$ square - feet.

Step2: Calculate total area of 2 rooms

Since there are 2 identical rooms, the total area $A_{total}=2\times A_1$. So, $A_{total}=2\times96 = 192$ square - feet.

Answer:

C. 192 square feet
