Answer 1

Answer:

3n + 18 = 5n {opposite sides of rectangle are equal and I'm equating them}

2n = 18n = 9

Substitute n = 9 in 3n + 18 = IN

IN = 3(9) + 18

IN = 27 + 18

IN = 45 Units

Answer 2

Answer:

opposite sides of a rectangle are equal ,

i.e , IN = SO

given IN = 3x + 18 , SO = 5x

=> 3x +18 = 5x

=>18 = 2x

=> x = 9 units

∴ IN = 3x + 18 = 3(9) +18 = 45 units
