Question

The length of the rectangular floor is twice its breadth . If the perimeter of the floor is 216m ,finds its length and breadth.

Answer 1

Answer:

Let the breadth of the rectangular floor be x m

it is given that the length is twice its breadth

So, length = 2x m

But, the perimeterof the rectangular floor is 216m

Now,

we have to find length and breadth of the rectangular floor

By using formula: 2 (l+b) = perimeter

According to the question

2(2x +x) = 216m

3x = 108m

x= 36m

Hence,

length of the rectangluar floor =36×2 m

= 72m

breadth of the rectangular floor = 36m
