Question

The length of a rectangle is twice its breadth. If perimeter of rectangle is 66cm find its length and breadth

Answer 1

Answer:

Let breadth be x

Then length=2x

Perimeter=2*length+breadth=66cm

=2*2x+x=66cm

=4x+x=66cm

=5x=66cm

=x=66/5cm

=x=13.2cm

So, breadth=13.2cm

Then, length=2*13.2cm=26.4cm
