Blueprints for a new house show Jim's bedroom is 1.5 inches by 2 inches. If the scale on the blueprints is 0.5 in = 4 ft, what are the actual dimensions of his room? What is the area of the room?

Actual dimensions: 12 ft by 16 ft.

Step-by-step explanation:

We have been given that blue prints for a new house show Jim's bedroom is 1.5 inches by 2 inches. The scale on the blueprints is 0.5 in = 4 ft.

Since 0.5 inches equals to 4 ft, therefore, 1 inch will be equal to 8 ft.

To find the actual dimensions of Jim's room, we will multiply 8 ft by each dimension as:

Therefore, the actual dimensions of Jim's room are 12 ft by 16 ft.

Area of Jim's room would be product of length and width as:

Therefore, the area of the room is 192 square feet.

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
