Question

1) The perimeter of a rectangle is 180 cm. If the length of the rectangle is twice its breadth, find its length and breadth. ​

Answer 1

Answer:

length = 60 cm

breadth = 30 cm

Step-by-step explanation:

Let the breadth be x

therefore,

• length = 2x

We know perimeter of rectangle = 2(L + B)

Therefore,

1. 2( 2x + x ) = 180 cm
2. 4x + 2x = 180 cm
3. 6x = 180 cm
4. x = 180/6
5. x = 30 cm

Now breadth = x = 30 cm

And length = 2x = 2×30 cm = 60cm
