Question

The length of the rectangle is increased by 50%. by what % would the width have to be decreased so as to maintain the same area?

Answer 1

in this problem

suppose that
length and breadth of rectangul is 100 unit

area = l × B

= 100 × 100 = 10000sq unit

if length increase then width decrease by

10000/150 = 66.66

decrease = 100 - 66.66

= 33.33%
