|
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 %. |
