Answer:
length = 25 cm , breadth = 12.5 cm
Step-by-step explanation:
let the breadth be b then the length = 2b
The perimeter is the sum of the 4 sides and is equal to 75 , then
b + b + 2b + 2b = 75 , that is
6b = 75 ( divide both sides by 6 )
b = 12.5
Then
breadth = 12.5 cm and length = 2 × 12.5 = 25 cm
