Answer 1

Step-by-step explanation:

Step-by-step explanation:

Length of the rectangle = 10 cm

Breadth of the rectangle = 8 cm

(i) When they are doubled,

⇢l = 10 × 2 = 20 cm

⇢b = 8 × 2 = 16 cm

Perimeter = 2(l + b)

= 2(20 + 16)

= 2 × 36

= 72 cm

(ii) When they are halved,

⇢l = 10/2 = 5 cm

⇢b = 8/2 = 4 cm

Perimeter = 2(l + b)

= 2(5 + 4)

= 2 × 9

= 18 cm
