Equation |x/2|+|y/2|=5 encloses a certain region on the coordinate plane. what is the are of this region?
Can someone please explain
I liked the question. probably the question meant the maximum area.
since |x/2|+|y/2| = 5
|x|+|y| = 10
we donot know the values of x and y. they could be +ve or -Ve. if so, x can be a minimum of -10 and a maximum of 10 and do does y. therefore,
x = -10 or 10
y = -10 or 10
if we draw a pricture, it becomes a square with a side of 10-(-10) = 20.
then the area = 20 x 20 = 400.
