The Length Of A Rectangle Is Increased By 60 %. By What Percent Would The Width Have To Be Decreased To Maintain The Same Area?

Answer»

Let length = 100 m. 

BREATH = 100 m. 

New length = 160 m.

New breath = x METERS 

Then, = 160 × x = 100 × 100 

(or) X = (100 ×100)/160 × 125/2 

Decrease in breadth = (100- 125/2) % = 37 ½ %.

Let length = 100 m. 

Breath = 100 m. 

New length = 160 m.

New breath = x meters 

Then, = 160 × x = 100 × 100 

(or) X = (100 ×100)/160 × 125/2 

Decrease in breadth = (100- 125/2) % = 37 ½ %.
