Question

THE LENGTH OF A RECTANGLE IS THREETIMES OF ITS WIDTH . IF THE LENGTH OF THE DIAGONAL IS 8√10M, THEN PERIMETER OF THE RECTANGLE IS

Answer 1

Step-by-step explanation:

Let breadth = x cm

Then, length = 3x cm

⇒x2+(3x)2=(810−−√)2⇒10x2=640⇒x2=64⇒x=8

So, length = 24 cm and breadth = 8 cm

∴ Perimeter = [2(24 + 8)] cm = 64 cm
