Question

96). The length of a rectangular is increased by 25%. By what percent would the width has to be decreased to maintain the same area?​

Answer 1

Answer:

The answer is written on the explanation section. Please check.

Explanation:

Let the length be 100

so, the area will be 100 X 100 = 10000.

suppose the length is increased by 25%

so now the length becomes 125.

Now let the new width be Y,

maintaining the same area the Y becomes = 10000/125 = 80

Now, the width has decreased (100-80=20)

so, the width has to be decreased to 20% to maintain the same area.
