Question

tenth of a rectangle is 16 cm less than twice its breadth if the perimeter of the rectangle is 100 cm find its length and breadth

Answer 1

Let the breadth of Rectangle be x
Then length will be 2x - 16

Perimeter = 2 (length + breadth)
100= 2 (2x -16 + x)
100=6x - 32
132=6x
22=x
Length= 2x- 16= 2×22- 16=28
Breadth= x = 22
Hope it helps

Answer 2

let the breath be X
therefore the length will be 2X - 16
perimeter of a rectangle is 2(L + B)
where L represents length and B represents breadth of the rectangle
therefore 2(2X-16+X)=100
3X-16=50
=>X=66/3=22cm
therefore breadth =22cm
Length=2(22)-16=28cm


I hope this will help you
