Question

the length of a rectangular feild is thirce of its breadth if the perimeter of the feild is 300m. then find the length and breadth of the feild​

Answer 1

Answer:

l=112.5 and b=37.5

Step-by-step explanation:

l=3b

2(l+b)=300

2(3b+b)=300

8b=300

b=37.5

l=3b=112.5

Answer 2

Answer:

112.5 is the correct answer

Step-by-step explanation:

Let the breadth of a rectangular field be 'x'.

As per the question,the length is thrice the length,then it will be '3x'.

The perimeter of the field is=300m

As we know,the perimeter of a rectangle is=2(l+b)

Then we should substitute,these criteria..That is=2(3x+x)=300

=)2*4x=300

=)8x=300

=)x=300/8

=)x=37.5

Here it is the breadth

The length is 37.5*3=112.5
