If the breadth of a rectangle is doubled and its length tripled, how many times larger will the new rectangle be compared to the original one?

Answer 1

use a specific example

B = 1

L = 2

area = BL = 2

double B to 2

triple L to 6

area = 12 which is 6 times the original area

it works for any value of B and L

BL = Area

2B(3L) = 6BL = 6 x original area
