Step-by-step explanation:
Let the length of a rectangle be x
so the breadth of a rectangle be
x × 2/3 = 2x /3
Perimeter of a rectangle
= 2 (l +b )
= 2 (x + 2x/3)
= 2 {( 3x + 2x)/3}
= 2 × 5x /3
= 10x/3
But perimeter of a rectangle = 180m (given)
A/q
10x /3 = 180
=》10x = 540
=》 x = 54
So length of a rectangle = 54m
and breadth = 2x /3 = (2×54)/3 = 36m
