Question

the perimeter of a rectangular plot is 156m .it's length is 3m more than its breadth. find the length and breadth of the plot.​

Answer 1

Answer:

Step-by-step explanation:

P = 156m

L = b + 3

P= 2l + 2b

2(b + 3) + 2b = 156

2b +6 +2b = 156

4b = 150

b = 150/4

b = 37.5

L = 37.5 + 3 = 40.5

Answer 2

Answer:

Length = 40.5m

Breadth = 37.5m

Step-by-step explanation:

Perimeter of the rectangular plot = 156m

Let the breadth of the rectangular plot be 'x' and length be 'x+3' respectively.

Perimeter of the rectangular plot = 2(l+b)

= 2(x+3+x)

=> 156m= 2(x+3+x)

=>156÷2 = x+3+x

=>78m= 2x+3

=> 78-3= 2x

=>2x= 75

=>x= 75÷2

=37.5m

Breadth of the rectangular plot= x= 37.5m

Length of the rectangular plot= x+3= 40.5m
