Answer:
50 cm is the length of the rectangle.
Step-by-step explanation:
Perimeter of square = 160m, then 1 side = 160/4 = 40m
So, the area of square = 40² = 1600m²
Since area of rectangle is smaller by 100m², then area of rectangle = 1500²
Based on four options, the length of rectangle will be 50cm and breadth will be 30 cm.
Hope it helps !

Answer:It will be 50 as
Side of square =160/4=40
Area of square =40*40=1600
Area of rectangle = 1600-100=1500
As, L*B =area
50*30=1500
30 is not in option so it will be breadth and 50 will be length
