Question

what will happen to the area of a rectangular if its length is doubled and breadth is tripled?1. 5 TIMES MORE THAN THE AREA OF THE OLD RECTANGLE2. ARE WILL REMAIN THE SAME3. 6 TIMES LESS THE AREA OF THE OLD RECTANGLE4. 6 TIMES MORE THE AREA OF THE OLD RECTANGLE

Answer 1

Area of rectangle = l* b
so, if length is doubled i.e. 2l
& breadth is triple i.e.3b
then area = 2l * 3b = 6lb

So, 4th one is correct i.e. area of rectangle will increase by 6 times.

Hope it will help you !!!

Answer 2

6 times more than the area of old rectangle.
That's because,
older rectangle area = l*b
new rectangle area = 2l*3b = 6lb
