Question

If the length of a rectangle is increased by 33.33%, by what percentage should the breadth be reduced to make the area same?

Answer 1

Answer:

25%

Step-by-step explanation:

Let the length be l and breadth be b

Area of rectangle = l * b

Now, length is increased by 33.33%

⇒ New length = l + l/3 = (4/3)*l

Let new breadth be x

Now area = (4/3)* l * x = l * b

⇒ x = (3/4)b

Percentage decrease = (1 - x/b) * 100% =(1 -0.75) * 100% = 25%
