Let the sides of rectangle be 5x and 4x

A/q,

4x * 5x = 500

➡ 20x² = 500

➡ x² = 500/20

➡ x² = 25

➡ x = 5

therefore length and breadth are 5x = 25 m and 4x = 20 m respectively.

Now, perimeter of rectangle = 2(l+b)

➡ 2 ( 25 + 20 )

➡ 2 ( 45 )

➡ 90m

so, option (c) is correct.

Hope it will help you !!!
