If the length of a rectangle is halved and its breath is tripled, what is the percentage change in its area??

A 50% increase

Step-by-step explanation:

Area = length x breadth

Let illustrate this with an example

original dimensions

length = 4

breadth = 5

area = 4 x 5 = 20

new dimensions

length = 4/2 = 2

breadth = 5 x 3 = 15

area = 15 x 2 = 30

Percentage change = 30 - 20 / 20 x 100 = 50%

b is the final answer! : )

the equivalent expression are always the hardest ones but you look at the gcf also
