Question

Length of a rectangle is three more than twice its breadth. If perimeter of that rectangle is 42 m. Find dimensions of the rectangle .

Answer 1

Step-by-step explanation:

Let breadth be x

then, l=2x+3

Perimeter=2(l+b)

=2(2x+3+x)

=4x+6+2x

=6x+6

Here, Perimeter = 42cm (Given)

6x+6=42

6x= 42-6

6x=36

x=36/6

x=6cm

Therefore, breadth=x=6cm and length=2x+3=2×6+3=12+3=15cm.
