Question

What is the percentage of change in area of ​​a rectangle if it is half the length and three times the width?​

Answer 1

Answer:

Let length be “a” and width be “b”.

hence, area = ab.

Now, length is halved; or “a/2”.

Width is tripled; or “3b”.

Area : (a/2)*(3b) = 3ab/2.

Now, (3ab/2)/(ab) = 3/2 = 1.5

hence, the increase in area is : (1.5 -1) = 0.5

then, 0.5*100 = 50% to convert to %.
