Question

The area of the triangle with vertices $(a,b),(x_1,y_1),(x_2,y_2)$ where $a,x_1,x_2$ are in G.P. with common ratio 'r' and $b,y_1,y_2$ are in G.P with common ratio ’s’ is

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

$a,x_1,x_2$ are in G.P. with C.R is 'r', $b,y_1,y_2$ are in G.P with C.R is $s,x_1=ar,x_2=a{r}^2,y_1=bs,x_2=b{s}^2$
