4
(ii) its breadth is doubled, the length remaining the same?
(iii) its length and breadth are both doubled?
ny?​

Answer 1

Answer:

let length of rectangle be l and if it is doubled it becomes 2 L

let breadth of rectangle be b

area of rectangle= length × breadth

2 L × b

2) let length of rectangle be l

let breadth of rectangle be b if breadth is doubled it becomes 2 b

area of rectangle = length× breadth

L× 2 b

3) let length of rectangle be l and if it is doubled it becomes 2 L

let breadth of rectangle be b if breadth is doubled it becomes 2 b

area= length ×breadth

2L × 2b

Step-by-step explanation:

Answer 2

Answer:

1. when its lenth is doubled and breath is same the area becomes double

2. when its breadth is doubled its area doubles

3. when both are doubled the area becomes 4 times the initial one
