Question

In the given figure the area of unshaded portion is 75%
of the area of the shaded portion. Find the value of x​

Answer 1

Step-by-step explanation:

area of whole part=x^2+130x+4000

area of shaded part=4000

area of unshaded part=x^2+130x

A/Q

x^2+130x=75/100*4000

x^2+130x-3000=0

x^2+150x-20x-3000=0

x(x+150)-20(x+150)=0

x=20,-150

hence value of x=20 metres.
