Question

If the length of the rectangle is increased by 10%then the area of the resulting rectangle ___ than the area of the original rectangle ​

Answer 1

Step-by-step explanation:

Original length = 120

Original width = 100

Original area = 120 x 100 = 12000

Let length increase by 10% or 1/10th

New length = 120 + 12 = 132

New width = 12000/132 = 90.9090

Hence, width decreases by :

(100 - 90.9090)/100 * 100 = 9.0909% or

9 1/11% or 1/11 part.
