Question

The sides of a rectangle are in the ratio of 4 : 5
i) by what fraction should the shorter side be increasing to make square?
ii) by what fraction should the longer side be decreasing to make it a square?

Answer 1

Answer:

let the lenght of the side of a rectangle be 4x and 5x

4xvis the smaller side of a lenght

to make 4x equal to 5x , we should add one more x into it.

the side should be increased by x/4x.

this, we increase the shorter side by 1/4th of it , then we get 4x equal to 5x .

Hence, it forms a square.
