Question

find the perimeter of rectangle whose length and breadth are in the ratio 3 : 5and area is 1500 m²​

Answer 1

Step-by-step explanation:

• Here, length and breadth are in ratio 3:5
• Let, the length and breadth of rectangle = 3x and 5x
• Now, Area of rectangle = length * breadth
• 1500 = 3x*5x
• 15x^2 = 1500
• x^2 = 1500/15
• x = √100 = 10 m
• So, length = 3x = 30 m and breadth = 5x = 50 m
• Perimeter of rectangle = 2(l+b) = 2(30+50) = 2*80 = 160 m
