Question

a room is 400 inches long and 300 inches wide. if the length is shortened to 10 inches how wide is the room

Answer 1

Explanation:

The room's width should remain unchanged at 300 inches.

If the question is asking room of the same area but length shortened to 10 inches, then the answer is 400*300/`10 = 12000 inches.

Answer 2

One thing the question lacking (The area of both room is same).

• New length=L=400-10=390
• Width be x

`\\ \rm\rightarrowtail 400(300)=390x`

`\\ \rm\rightarrowtail 120000=390x`

`\\ \rm\rightarrowtail x=307.69`
