The line 5x + 2y = 20 cuts the axes at points P (on the x-axis) and Q (on the y-axis). O is the origin. Find the area of triangle OPQ (in square units).

Question

Accepted Answer

20. x-intercept: y=0 -> 5x=20 -> x=4, so P(4,0). y-intercept: x=0 -> 2y=20 -> y=10, so Q(0,10). Area = 1/2(4)(10) = 20 sq units.

The line $5 x + 2 y = 20$ cuts the axes at points P (on the $x$ -axis) and Q (on the $y$ -axis).
O is the origin.
