Question

the length of a rectangle field is twice it's breadth. if the perimetre of the field is 228 metres. find their present ages ​

Answer 1

Answer:

Step-by-step explanation:

Let the breadth of rectangular field be x.

Then its length will be 2x.

Given, perimeter =288=2(l+b) m

Therefore, 2(x+2x)=288

6x=288

x=48 m

Now, length will be 2x=2×48=96 m.

Therefore, length and breadth of a rectangular field are 96 m and 48 m respectively

Answer 2

Answer:

Breadth = 38m

Length = 76m

Step-by-step explanation:

Let the length be denoted by l & breadth be denoted by b.

According to question, l = 2b

Perimeter of field = 228 m = 2 (l+b)

=> 2b+b = 114

=> b = 114/3 = 38m

So, l = 2b = 76m

Hope this helps.....
