The Length Of A Rectangular Plot Is Increased By 25%. To Keep It’s Area Uncharged The Width Of The Plot Should Be? |
|
Answer» LET the length be X metres and BREADTH be y metres Then it’s area =(xy)m2 New length =(125/100 x)m =(5x/4)m. Let the new breadth be 2 metres Then xy 5x/4 x 2 => 2 = 4/5 y Decreased in WIDTH =(y -4/5 y) = y/5 metres Decreased % in width =(y/5 x 1/y x 100)% = 20%. Let the length be x metres and breadth be y metres Then it’s area =(xy)m2 New length =(125/100 x)m =(5x/4)m.
