Question

calculate the area bounded by the line X + Y is equal to 10 and both the co-ordinate Axes

Answer 1

we have line x+y =10
convert. it in intercept form... I. e., in
(x/a)+y/b =1 form
where a=x intercept, b=y intercept
so
x+y=10
(x/10)+(y/10)=1
I. e., line cuts 10units on X axis and 10 on y axis
{{{............if u don't know this form,, u can treat it as in putting x=0,y=10 and y=0,x=10..i. e., line is cutting X and y axis at (10,0)and(0,10))....................................}}
area =(1/2)*b*h
=(1/2)*10*10=50unit sq.
