Answer:
a=2
b=14
Step-by-step explanation:
(P) =360
(l) =?
(b) =?
so, let the breadth be x
let the length be 2x
Perimeter of rectangle=2(l+b)
360 =2(2x+x)
360/2 =2x
180/2 =x
60 =x
x =60
ATQ
Breadth = 60
length= 60 ×2
=180
Multiply it out.
I believe the answer would be 15x^2 - 20x.
However, functions is not my forte.
Soooo
yeah
