Question

5. If the breadth of rectangle is doubled and length tripled, then the area becomes​

Answer 1

(1)area gets doubled if length is doubled while breadth remains same.

for eg let length be 2 and breadth be 4

area = L×B= 2×4=8

AFTER LENGTH IS DOUBLED

L=2×2=4,B=4

area=4×4=16

as we can see 16 is double of 8.

(2)same happens when breadth is doubled and length remain same.

(3) double the length and breadth

L=2×2=4,B= 4×4=16

area=16×4=64

so area increases by 4 times.
