Question

The area of rectangular Park is 402m2.length of the plot is 2 more than thrice it's breadth

Answer 1

B = 6m L=20m

Step-by-step explanation:

let breadth of rectangular plot be 'b'

and length be L

L = 3b +2

area is L × B = 120

(3b +2)b = 120

3b^2 +2b - 120 =0

3b^2 +20b -18b -120 =0

b (3b +20) -6 (3b +20) =0

(3b + 20)(b -6) =0

hence breadth = 6m

length = 3(6) +2 =20m
