Question

The length of a rectangular park is 8 m more than its breadth .if area of the park is 240 m.then find the length and breadth of the park

Answer 1

Answer:

Let breadth = x m

Length = (x+8)m

A/q,

x(x+8) = 240

x² + 8x -240 = 0

x² - 12x + 20x - 240 = 0

x(x-12) + 20(x-12) = 0

(x-12)(x+20) = 0

x = 12m = Breadth

length = 20m

Answer 2

Answer:

length is 20m

breadth is 12m

Step-by-step explanation:

let the breadth be x

then length will be x+8

area=length x breadth

=x (x+8)=240

x^2 + 8x -240 =0

solving for x, we get x=12

so,breadth is 12m

and length is 12+8=20m
