Question

length 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 breadth=A,

then

length=2A-16,

now according to the question, we have

2(length+breadth)=100 cm,

2(2A-16+A)=100,

3A-16=50,

3A=50+16,

then

3A=66,

then

A=22,


hence

breadth=22 cm,

length=2×22-16,

=44-16=28cm
