Answer: (C) 4
Have a good day.
Area=hxw
h=a/w
h=120/10
12=120/10
h=12
Step-by-step explanation:
We know that if (h,k) is the center of any circle and whose radius is = r then its equation is :
Given, the equation of circle
By comparing, we will get,
h = -2
k = 3
So, center of the circle is ( -2,3)
We know that area of rectangle its equail A=l*w.
We know that length is 4 times greater than width, so we can say
l=4x and w=x
Knowing that area A=144 we can say
4x*x=144
-
w=6 - its the width
l=6*4=24 - its the length
