1. Rick renovated his home. He made his bedroom 40% larger (length and width) than its original size. If the original dimensions were 144 inches by 168 inches, how big is his room now if measured in feet?

Respuesta :

Answer:

New dimension: 16.8 feet by 19.6 feet.

Step-by-step explanation:

Given that,

The original dimensions of the room were 144 inches by 168 inches. Rick renovated his home. He made his bedroom 40% larger than its original size.

40% of 144 = 57.6

New length is 144 + 57.6 = 201.6 inches

40 % of 168 = 67.2

New breadth is 168 + 67.2 = 235.2 inches

Since, 1 foot = 12 inch

201.6 inches = 16.8 feet

235.2 inches = 19.6 feet

The new dimension of the room is 16.8 feet by 19.6 feet.
