Answer: Breadth = 3 ; Length = 6
Step-by-step explanation:
Let the width be 'x'
Length = 2x
Perimeter = 18
Perimeter formula for rectangle = 2 ( length + breadth )
Substitute:
2 ( 2x + x ) = 18
2 ( 3x ) = 18
3x = 9
x = 3
Therefore, the width is 3.
The length is 2x = 2(3) = 6.
To check, find the perimeter:
2 ( 3 + 6 )
= 2 ( 9 )
= 18.
The perimeter is correct, therefore our answer for the width and breadth of the rectangle is correct.
