Answer 1

Answer :-

• Let the common multiple be x
• Let the length be 4x
• Let the breadth be 3x
• Perimeter is = 154 cm

Solution :-

Perimeter of rectangle = 2 ( l + b )

154 = 2 ( 4x + 3x )

154 = 2 ( 7x )

154 = 14x

154/14 = x

11 = x

So,

Length = 4 × 11 = 44cm

Breadth = 3 × 11 = 33cm

Answer 2

answer is

length=44

breadth =33
