Question

The length of a rectangle is 3 m less than twice its breadth. Find the length and breadth of the rectangle, if its perimeter is 18 m.

Answer 1

Answer:

LET THE BREATH OF RECTANGLE =X

THEN THE LENGTH= 2X-3

FORMULA FOR PERIMETER OF RECTANGLE :::

$p = 2 \times l + b$

PERIMETER =2(LENGTH+BREATH)

PUTTING VALUE

18=2[(2x-3)+x)

18=2(3x-3)

18=6x-6

6x=24

x=4

LENGTH OF RECTANGLE=(2X-3)=(2×4-3)=(8-3)=5 M

BREATH OF RECTANGLE 4M.
