Well I’m back with another question-
So uh I’m grasping the concept of this subject still since it’s gotten a bit more advanced ,so please don’t judge haha
Ok but here’s the question I need help with!

When Mr. Watson purchased his house, the dining room measured 20 feet long and 16 feet wide. Before he moved in, Mr. Watson paid a company to increase the length of the dining room by 4 feet.

Part A:
How much greater is the area of the new dining room than the old dining room?




Part B:
In the original room, an 8x10 rug covered a fractional part of the floor. For the new dining room, Mr. Watson wants to buy a rug to cover that same fractional part of the floor.

What could be the length and width of the new rug?


If you help, I will mark brainliest! Thank you.

Respuesta :

Part A: The area of the new dining room is 64 feet greater than the old dining room.

You need to know the formula of finding the area, which is length times width. First, you find the area of the old dining room (320 ft) and the new dining room (384 ft). Then, you subtract the areas (384-320) to get 64 feet.




Part B: The length and width of the new rug could be 12x10. The length of the original dining room was increased by 4 to create the new dining room. So, in this problem, you just add the length of the original rug (8 feet) by 4 to get 12.


Hope this helps.
