Question

the length of a rectangular field exceeds by 5 metre if the perimeter of the plot is 142 metres find the length and breadth of the plot

Answer 1

let the breadth be x then length wiil equal to x+5 so
2(x+5+x)=142
=2(2x+5)=4x + 10=142
4x=132
=132/4=x
=33=b
l=33+5=38

Answer 2

Answer:

Step-by-step explanation:

Hi! Krishna is here if you need any help than please rate me and give me 5 heart and my no. 8114476137.

So, the explanation will be:

= let the breath be x

then,length will equal to x+5(;because"field is exceeds by 5 metre ")

So,

=2(x+5+x)=142

=2(2x+5)=142

=(4x+10)=142

=4x=132

= x=132/41

= x=33(which is the breadth)

so, length=breadth+5

= length=33+5

= length=38

Hence, for verify =2(l+b)

=2(33+38)

=2*71

=142 which was the perimeter.
