Question

The length of a rectangular field is thrice its breadth and its perimeter is 240 m. find length and breadth.​

Answer 1

Answer:

90m

Step-by-step explanation:

Let l be the length and b be the breadth

 So according to the given condition l=3b

Perimeter=2(l+b)

So,2(3b+b)=240m

b=30m

So l=90m

Answer 2

Answer:

Let l be the length and b be the breadth

So according to the given condition l=3b

Perimeter=2(l+b)

So,2(3b+b)=240m

b=30m

So l=90m
