Question

the length of a rectangular plot is 8 m more than its breadth.if the perimeter of the plot is 64 m , find its length and breadth

Answer 1

Let length be x and breadth be y

ATQ,
x = y+8

2(x+y) = 64

so, y+y+8 = 32

2y= 24

y=12

so, length= 20 and breadth=12

Answer 2

Let the breadth of the plot be x
Then,length will be x+8
ATQ
The perimeter of the plot is 64m
The perimeter of rectangle is 2(l+b)
So,
2(x+8+x)=64
2(2x+8)=64
4x+16=64
4x=64-16
4x=48
x=48\8
x=6
Length is x+8=6+8=12m
Breadth is 8m
