Question

The boundary of a rectangular frame is decorated with a 150cm long ribbon .Find the dimensions of frame of its length is twice its breadth

Answer 1

Answer:

length =50cm,breath =25cm

Step-by-step explanation:

Perimeter of rectangle =2×(l+b)

Here , length is twice it's breath

Let dimensions be x

So, length =2x and breath=x

150cm=2×2x+x

150cm=6x

150/6=x

25cm= x

So,

breath is x=25cm and

length is twice so

2×x=2×25

50cm
