Let the breadth of the rectangle be x.
Then length will be 2x-16.
Perimeter = 2( length+breadth)
Length+ Breadth = 50
x+2x-16 = 50
3x-16 = 50
3x = 50+16
x = 66÷3
= 22
Length = 2 x 22 - 16 = 44 - 16 = 28 cm
Breadth = 22
Hope it helps u....

Answer:
Let the breadth of rectangle be x
Length of rectangle= 2x - 16
Perimeter of rectangle= 2(L+B)
= 2(2x -16)
Given perimeter = 100cm
2(2x-16)= 100
2x -16 = 100/2
2x -16 = 50
2x = 50+16
2x = 66
x= 66/2
x= 33
therefore breadth of rectangle is 33cm.
Length of rectangle 2(33)-16
66-16=50.
