area of rectangular plot
= l × b
2400 = x × 3/2x
2400 = 3/2 × x^2
2400 × 2/3 = x^2
1600 = x^2
40 = x.
therefore, b = 40m
l = 3/2 × 40 = 60 m
Perimeter = 2 (l+b)
= 2 (40 + 60)
= 2 (100)
= 200 m
Therefore answer is 20 m
= l × b
2400 = x × 3/2x
2400 = 3/2 × x^2
2400 × 2/3 = x^2
1600 = x^2
40 = x.
therefore, b = 40m
l = 3/2 × 40 = 60 m
Perimeter = 2 (l+b)
= 2 (40 + 60)
= 2 (100)
= 200 m
Therefore answer is 20 m
